Building Memorials and Domes over the Graves of
Awliya Allah is very much liked by Allah ( سبحانہ و تعا لی )

Salafis and their offshoot groups like Deobandis, Tabhlighees, Jamaat-e-Islami and like minded, have played a big role in taking Muslims away from the straight path of Islam. They pickup Ahadith meant for un-believers and impose them on Prophet Mohammad (صلى الله عليه و آله وسلم), Sahabah (رضئ اللھ تعالی عنہم اجمعین ) and Awliya Allah.

The most vulgar, beastly and inhuman treachery in the history of mankind is the desecration and destruction of the pious Graves of the family members of Prophet Mohammad (صلى الله عليه و آله وسلم), Sahabah(رضئ اللھ تعالی عنہم اجمعین ), Imams and Awliya Allah in Arabian Peninsula in the hands of fanatic Wahhabis. It is reported that Gasoline was poured after destroying the grave of Amina Bint Wahb (رضئ اللہ تعالی عنہا), the mother of Prophet Mohammad (صلى الله عليه و آله وسلم). (Reference book 'Grave Destruction and Desecration' by Shaikh Al-Sayyid Yusuf al-Rifai - translated in English by Shaikh G.F. Haddad).

They also destroyed Prophet Mohammad's (صلى الله عليه و آله وسلم) house in Makka where he lived for 28 years with his family and built a Public Toilet on it.

The same Wahhabis acted differently when the Sufi cemetery was razed by Syrian Salafis to make way for the University of Damascus and its campus in that city. The whole world knows that King Abd al-Aziz Ibn Sa`ud of Saudi Arabia intervened personally to preserve intact the graves and tombs of Ibn Taymiyya and his student Ibn Kathir.



Ibn Taymiyya's Grave, near Baramkeh, Syria inside Damascus University campus, behind a maternity hospital.

This proves that Wahhabis are the worst enemies of Prophet Mohammad (صلى الله عليه و آله وسلم) and Islam. We pray Allah(سبحانہ و تعا لی) to save our Prophet (صلى الله عليه و آله وسلم) and Islam from the oppression of these people.

We have provided authentic Ahadith below which confirm the fact that building of elevated Graves of Sahabah (رضئ اللھ تعالی عنہم اجمعین ) and Awliya Allah is Sunnah and is the practice of Salaf and Khalaf and their followers for over 1400 years.

Prophet Mohammad (صلى الله عليه و آله وسلم) ordered his pious mazaar to be within a secured room with surrounding walls and roofing. After making the mazaar of Prophet Mohammad (صلى الله عليه و آله وسلم)Sahabah did not destroy the room. As a matter of fact it was reinforced and ultimately a large tomb was built on Raudhatun Nabi (صلى الله عليه و آله وسلم).

(1) It is in Hadith - Narrated Abu Bakr bin 'Aiyash (رضئ اللہ تعالی عنہ): Sufyan at-Tammar (رضئ اللہ تعالی عنہ) told me that he had seen the Grave of the Prophet (صلى الله عليه و آله وسلم)elevated and convex. (Bukhari - Book 23, Hadith 473).

All Muslims of the world know that the three pious graves inside Masjid-e-Nabawi (صلى الله عليه و آله وسلم) are elevated, considerably higher from the ground. These remain the same from the earliest times as reported in the above Hadith.

(2) It is in Hadith - Narrated Al-Qasim ibn Muhammad ibn AbuBakr(رضئ اللہ تعالی عنہ) : I said to Ummul Momineen Aisha (رضئ اللہ تعالی عنہا)! Mother, show me the Grave of the Apostle of Allah (صلى الله عليه و آله وسلم) and his two Companions (رضئ اللھ تعالی عنہم). She showed me three Graves which were neither high nor low, but were spread with soft red pebbles in an open space (in the secured room). (Abu Dawood Book 20, Hadith 3214).

The above Hadith nails the lies of Wahhabis / Salafis / Deobandis and their like minded groups. The Wahhabis have destroyed and flattened the graves (without a trace) of all family members of Prophet Mohammad (صلى الله عليه و آله وسلم)Sahabah (رضئ اللھ تعالی عنہم اجمعین ), Imams and Awliya Allah. There were hundreds of thousands pious graves of Sahabah in Arabian peninsula. Now, there is none available.
There is no Hadith or Quranic Verse which says that the Graves of the family members of Prophet Mohammad (صلى الله عليه و آله وسلم), Sahabah (رضئ اللھ تعالی عنہم اجمعین ) should be destroyed and flattened to the ground without a trace.

(3) It is in Hadith - Narrated by Abu Dawood and al-Bayhaqiin al-Kubra (3:412) with fair chains. Ibn Hajar, Talkhis al-Habir (2:134) and Ibn al-Mulaqqin, Tuhfat al-Muhtaj (2:29): "Prophet (صلى الله عليه و آله وسلم) asked a man (Sahabi) to place a rock on top of Ibn Maz`un's (رضئ اللہ تعالی عنہ) Grave. When he was unable to move it (as the rock was too large), Allah's Apostle (صلى الله عليه و آله وسلم) rolled up his sleeves and helped him and the whiteness of his arms was visible (to everyone). Ibn Maz`un (رضئ اللہ تعالی عنہ) was the first of the Muhajirin buried in Baqi al-Gharqad. Hadhrat Ibrahim (رضئ اللہ تعالی عنہ),the Prophet's (صلى الله عليه و آله وسلم) son, was buried next to him. (Abu Dawood, al-Bayhaqi, Ibn Hajar, Ibn al-Mulaqqin).

The above Hadith was also mentioned by Bukhari under Chapter titled 'Stalk on the top of the Grave'.

Ibn Hajar said in Fath al-Bari (3:256=1959 ed. 3:223): "Al-Bukhari narrated this Hadith with its (sound) chain in al-Tarikh al-Saghir (1:42) "

The above Hadith clearly establishes the fact that it is Sunnah to make the graves of Sahabah and Awliya Allah higher and elevated from the ground and prominent to keep them as memorials for the following generations. It is also important to visit these pious graves for Dua. If you remove these important memorials, then you will deprive the entire Ummah of the Dua of these pious souls.

(4) Some people quote a Hadith of the Prophet Mohammad(صلى الله عليه و آله وسلم) in which he ordered Ali (رضئ اللہ تعالی عنہ)to "go and destroy every over-sized grave." This Hadith is in the Sahihayn, Sunan, and Musnad with various wordings.

The above Hadith is misinterpreted by Wahhabis. There is no exception to this Hadith; the Wahhabis have misinterpreted the entire Quran and Ahadith books. We have cautioned Muslims, time and again, in our articles that one should learn Islam in the company of an authentic Shaikh of Ihsan. We should not read Quran and Ahadith independently and deduce rules based on our limited understanding. If we do that, there is a strong possibility that we misunderstand the meanings and go astray.

Imam Sufyan al-Thawri rightly said: "(the wordings of) this Hadith may misguide people except those who possess (Sahi) understanding (of Islam)."

Therefore, the correct understanding of the Hadith is, Prophet(صلى الله عليه و آله وسلم) asked Ali (رضئ اللہ تعالی عنہ) to destroy all graves of non-believers (pagans) which were high on the ground. This correct understanding is based on the following Hadith of Prophet Mohammad (صلى الله عليه و آله وسلم).

(5) It is in Hadith - Narrated Anas (رضئ اللہ تعالی عنہ): When the Prophet arrived in Medina.... he ordered that a Mosque should be built and sent for some people of Banu-an-Najjar and said, "O Banu an-Najjar! Suggest to me the price of this (walled) piece of land of yours." They replied, "No! By Allah (سبحانہ و تعا لی )! We do not demand its price except from Allah (سبحانہ و تعا لی )." Anas (رضئ اللہ تعالی عنہ) added: There were Graves of pagans in it and some of it was un-leveled and there were some date-palm trees in it. The Prophet (صلى الله عليه و آله وسلم) ordered that the Graves of the paagans be dug out and the uneven land be leveled and the date-palm trees be cut down . (So all that was done).(Bukhari Book #8, Hadith 420).

Ibn al-Jawzi in at-Tahqiq said of the above Hadith of Ali (رضئ اللہ تعالی عنہ) (mentioned at No. 11 above) as follows.

"This (Hadith) is understood to refer to the elevated (Pre-Islamic) tombs they (Paagans) used to build with high and beautiful structures." (Al-Zayla'i mentioned it in Nasb al-Raya).

Prophet Mohammad (صلى الله عليه و آله وسلم) wanted to destroy Idol worship in all its formats. He wanted to clean all traces of Idol worship. This is the reason he removed all idols from Kabatullah and ordered Ali (رضئ اللہ تعالی عنہ) to level all over-sized graves of un-believers.

Wahhabis did exactly the opposite of what Prophet Mohammad (صلى الله عليه و آله وسلم) did.

First they created a sky God for themselves, an idol bigger than all planets put together, who has hands, fingers, shins, eyes, face, and other organs. They call it Allah and claim that this idol is physically sitting over the skies on a big chair. They translate the Kalima as "There is no Deity save Allah and Mohammad (صلى الله عليه و آله وسلم) is His Messenger". When they say Allah is one, they mean that theBig Deity or Idol sitting on the skies is one, unique and no other Deity or Idol is like him. They worship this idol 5 times a day. They claim that this Idol walks down to the first sky every night and then goes back to his chair. They consider that this Idol has sent all Messengers and all scriptures. (La haula wala quwwata illa billah).

Hindus worship a similar God whose name is Vishnu or Brahma. Thus, the Hindu God Vishu and Salafis Sky Godare identical in Essence and Attributes; the only difference isSalafi Sky God is single, while Vishnu is married.

Ibn Taymiyaah who started Salafism, has also invented a theory of Idol Tawheed or Oneness of their Sky God. They say (i) Tawheed-ar-Rububiyya, (ii) Tawheed al-Uloohiyya, and(iii) Tawheed-al-Asma-was-Sifaat.

In Tawheed-ar-Rububiyya, they claim that their Sky God is "Rabb" or Sustainer of all creatures and human beings in the Universe. In Tawheed-al-Uloohiya, they claim that their Sky God is Divine. They prostrate in front of that Deity. They say that they only ask from their Sky God and from no one else. They demand all Muslims to ask from their Sky Idol God. Whoever does not do that, they call him Mushrik. InTawheed al-Asma-was-Sifaat, they claim that their Sky God is 'compassionate, merciful and all that.

After the creation of their Sky God, they rejected the Ijma (consensus) rule. They rejected all Imams of Fiqh and claimed that they follow Quran and Sunnah by their self study without any teacher or Imam. Then, they started destroying all original traces of Islam from Arabian Peninsula. Theydestroyed the pious graves of Prophet Mohammad's (صلى الله عليه و آله وسلم) family members, Sahabah (رضئ اللھ تعالی عنہم اجمعین ) and Awliya Allah from Arabian peninsula. They also destroyed all Islamic relics, houses, mosques and anything which had any trace of original Islam. They captured the holy places of Islam, Kabatullah and Majid-e-Nabawi. They renamed the country as Kingdom of Saudi Arabia and started constructing so called modern buildings in Hijaz and other places for commercial religious tourism. There were thousands of pious graves of Sahaba (رضئ اللھ تعالی عنہم اجمعین)and adjacent mosques throughout Arabian Peninsula. Now, nothing is there, everything has been destroyed. New buildings have been constructed over these sacred graves and we do not know how many of these graves were turned into sewerage lines and toilets in that country.

The graves of Sahabah (رضئ اللھ تعالی عنہم اجمعین) at Badr andUhad were destroyed and converted into parking lots. Now Salafis walk over these graves with their shoes and Cars are parked over the pious graves of Sahabah (رضئ اللھ تعالی عنہم اجمعین) who gave their lives to strengthen Islam. An ATM facility is built at the place of Hadhrat Abu Bakr Siddique's(رضئ اللہ تعالی عنہ) mosque in Makka. All this was done to establish and consolidate the religion of their Sky God.

Since they wanted to bury Islam completely and build at this grave the religion of their Sky God, they changed all Hadith books. Initially, all Ahadith which were against their self fabricated new Aqeedah, were declared as 'fabricated' (Maudu) in all Hadith books. Later they started removing these Ahadith altogether. Al-Baani, who is considered as greatest Muhaddith of Salafism, removed 83 chapters from the most authentic Islamic Hadith book 'Bukhari' and published a new book titled "Sahih Adab Al Mufrad". Similar is the case with other Ahadith books. Now, they claim they will accept only those Ahadith which have been approved (read altered) by Al-Baani. Now-a-days, every Hadith they quote, they write (with it) that it is "approved by Al-Baani'. Meaning, Salafis do not consider Bukhari, Muslim and others as authentic Imams of Ahadith. Now-a-days, they have started writing "Imam Al-Baani" and argue that he is the only authority in Hadith literature and no one else is greater than him (Astaghfirullah). They also changed the meanings of most of the Quranic verses and published a "Noble Quran"which contains meanings of Quranic verses as per their self fabricated Sky God Aqeedah. We pray, Allah ( سبحانہ و تعا لی ) tosave Muslims from this fitnah.

There are three most prominent Scholars of Salafis (Sky God Worshipers) of recent times who have done a great deal in changing the original Islam and its authentic books, (1) Ibn Baz, (2) Al-Uthaymin, and (3) Al-Baani.

Zakir Naik, founder of Islamic Research Foundation, India, who is banned from giving lectures in UP, India and UK for his controversial speeches, and Asrar Ahmad, (1932 – 2010),founder of Tanzeem-e-Islami, Pakistan, who was banned from appearing on QTV, Pakistan and 'Vision TV, Canada' for his outrageous remarks against Sahabah, are two prominent followers of Salafism who have played a big role in spreading Salafism (Sky God Religion) and taking millions of innocent Muslims away from the straight path of Islam.

Some people may argue that Salafis beliefs are as per Quran and Ahadith. This argument is wrong because if their beliefs were as per Quran and Ahadith, then there was no need for them to change all Ahadith books and the meanings of Quran. Why are they destroying everything, all Ahadith books, the entire Islamic heritage? Why are they insulting and degrading the Prophet of Islam (صلى الله عليه و آله وسلم), Sahabah, Imams and Awliya Allah? Why are they branding real Muslims as Mushrikeen? Because they know that this is the only way to establish and strengthen their Sky God Religion in the world. Their long term strategy for the past 100 years has worked and they have been successful to a large extent in their pursuit.


(6) It is in Hadith - Narrated 'Ali (رضئ اللہ تعالی عنہ): The Prophet (صلى الله عليه و آله وسلم) said, "Do not tell a lie against me for whoever tells a lie against me (intentionally) then he will surely enter the Hell-fire." (Bukhari - Book #3, Hadith 106).

They did not stop at that. They exported Salafism (Sky God religion) to other Islamic countries of the world with the help of massive petro-dollars wealth and have attempted to destroy original Islam from the face of the Earth.

Salafis, Deobandis, Tablighees and their like minded groups should know that whatever they do, they will not be able to destroy Islam. This is the Deen which will be protected by Allah ( سبحانہ و تعا لی ) till the day of resurrection.

(7) It is in Hadith - Abu Qatada (رضئ اللہ تعالی عنہ) narrates that Prophet (صلى الله عليه و آله وسلم) said: "When you are a custodian of any dead, give them a fine shroud because they (the dead believers) visit one another place and meet one another(Tirmidhi, Ibn Majah and Baihaqi).

The above Hadith establishes the fact that the pious Muslims and Awliya Allah, after their deaths, visit each other's graves. When they come to the grave, they look at their intact bodies and the Shroud (Kafan). If the shroud is good, it will be appreciated, if not, they may talk about the miserliness of the relatives and children of the dead believer.

The above Hadith also establishes the fact that the grave of Awliya Allah should be made elevated and should be well protected by walls and roof over them. We should provide for their maintenance and proper cloth covering. These protected graves are also appreciated among the Awliya Allah after their deaths. If you leave them flattened to earth without proper protection, the rain water seeps into the graves and this type of neglect on the part of relatives is seen as disrespect and serious negligence for which they may be questioned and punished in Hereafter.

(8) It is in Hadith - Quoted by Ibn al-Qayyim al-Jawziyya in his book 'Kitab ar-Rooh'. It is narrated by Ibn Uyaina's maternal cousin Fudayl that he got very sad on the death of his father and he used to do Ziyarah of his Grave everyday. However, by the will of Allah ( سبحانہ و تعا لی ), after sometime he did not visit it often. Once when he came and sat by the side of the grave of his father, (after some time) he fell asleep and saw in the dream that his father's grave has been opened and he is covered in a sheet with a look which is of dead people. Seeing this, he started to cry. (His father) asked : My son why did not you visit me everyday? He replied : Are you aware of my visitation? (His father) said: I was aware of your arrival every time and your visitation and your Dua is a source of happiness not only for me but also those who are buried near me. After this I (again) started to visit his Grave very often. (Kitab ar-Rooh written by Ibn al-Qayyim al-Jawziyya).

(9) It is in Hadith - "Prophet Mohammad (صلى الله عليه و آله وسلم)said - The Prophets are alive and they pray in their graves"; narrated by al-Mundhiri and al-Baihaqi who classified it as authentic (Sahih).

(10) It is in Hadith - The Prophet (صلى الله عليه و آله وسلم) told Mu'adh Ibn Jabal (رضئ اللہ تعالی عنہ) to visit his Grave whenever he would return from Yemen. And he (صلى الله عليه و آله وسلم)promised his intercession to those who would do so. (Musnad Ahmad with two sound chains as stated by al-Haythami, al-Bazzar, al-Tabarani in al-Kabir and Musnad al-Shamiyeen. Ibn Abi Asim in al-Ahad wal-Mathani and as-Sunna. Ibn Hibban in his Sahih, Baihaqi in al-Sunan al-Kubra).



The Awliya Allah and un-believers are not treated as equals In the court of Allah ( سبحانہ و تعا لی ).

(11) It is in Quran - أُولَـٰئِكَ هُمُ الْمُؤْمِنُونَ حَقًّا ۚ لَّهُمْ دَرَجَاتٌ عِندَ رَبِّهِمْ وَمَغْفِرَةٌ وَرِزْقٌ كَرِيمٌ [Meaning - Those are they who are in truthbelievers. For them are Grades (of honour) with their Lord, and pardon, and a bountiful provision. (Al-Anfal - 4)]

(12) It is in Quran - وَلَوْ تَرَىٰ إِذْ يَتَوَفَّى الَّذِينَ كَفَرُوا ۙ الْمَلَائِكَةُ يَضْرِبُونَ وُجُوهَهُمْ وَأَدْبَارَهُمْ وَذُوقُوا عَذَابَ الْحَرِيقِ [Meaning - If you could seehow the angels receive those who disbelieve, smiting faces and their backs and (saying): Taste the punishment of burning! (Al-Anfal - 50)]

The above Quranic verses clearly specify that there are grades of honor and rewards for pious Muslims in Hereafter; while un-believers and hypocrites are treated as criminals and are punished for their crimes. Therefore, the Graves of pious believers are not to be treated on par with the Graves of un-believers and hypocrites.

For instance, mosques, churches and temples are built as massive structures, but these buildings are not treated alike. Mosque is a place where we pray Allah( سبحانہ و تعا لی ); whereas Churches and Temples are the places where idols are worshiped. Therefore, we are not allowed to go to temples and churches but are required to go to mosques for congregation prayers 5 times a day. Similarly, the Graves of un-believers and hypocrites are the places of apostasy, therefore, we should not visit them, we should not build these graves higher from the ground or make domes over them.

However, this is not the case with the Graves of pious Muslims and Awliya Allah. It is in Ahadith that the Graves ofSahabah (رضئ اللھ تعالی عنہم اجمعین ) and Awliya Allah are turned into gardens of Paradise, even their dead bodies are protected by Allah ( سبحانہ و تعا لی ). Therefore, building tombs over them is very much liked by Allah ( سبحانہ و تعا لی ) and His Apostle(صلى الله عليه و آله وسلم) which is proved from the above Quranic verses and Ahadith.

(13) It is in Hadith - Narrated 'Abdullah bin Zaid Al-Mazini: Allah's Apostle (صلى الله عليه و آله وسلم) said, "Between my house and the pulpit (in Masjid-e-Nabawi) there is a Garden of the Gardens of Paradise." (Bukhari - Book 21, Hadith 286).

There are differences of opinion among Imams of fiqh about the size and shape of the grave. All Imams and scholars are right in their opinions. Those who say that the grave should be around 1 feet higher from the ground and flattened, actually refer to the graves of general Muslims in a common graveyard whose bodies get decomposed over a period of time.
Those who say that the grave should be higher, elevated and rounded above the ground, refer to the graves of Prophets, Sahabah and Awliya Allah. This is important because the bodies of Prophets, Sahabah and Awliya Allah remain fresh and in tact in their graves, therefore, we should make arrangement that the grave is considerably higher from the ground so that rain water does not seep into the grave. These are the graves of the beloveds of Allah ( سبحانہ و تعا لی ), therefore it is important that they are surrounded by grills, walls and roof to protect them from buffalo, dogs and other wandering animals.

(14) It is in Hadith - Narrated by Abu Hurayra (رضئ اللہ تعالی عنہ) "The Prophet (صلى الله عليه و آله وسلم) came to the graveyard and said: "Peace be upon you, O' abode of a people of believers! We shall certainly join you, if Allah ( سبحانہ و تعا لی )will. How I long to see my brothers! "They said: " O' Messenger of Allah (صلى الله عليه و آله وسلم), are we not your brothers?" He replied: "You are my Companions! As for my brothers, they are those who have not yet appeared." They said: "How will you recognize those of your Community who had not yet appeared (in your time) O'Messenger of Allah (صلى الله عليه و آله وسلم)?" He replied: "Suppose a man had horses with shiny white marks on their foreheads and legs: would he not recognize them among other horses which are all black?" They said: "Yes O'Messenger of Allah (صلى الله عليه و آله وسلم)!" He continued: "Verily, they (my brothers) shall be coming with shiny bright foreheads and limbs in view of their ablutions, and I shall precede them to my Pond." (Muslim, Nasa'i, Malik, and Ahmad).

(15) It is in Hadith - It is reported that Prophet Mohammad (صلى الله عليه و آله وسلم) once said after the salat - " O ' People! Listen to this, understand it and know it. Allah ( سبحانہ و تعا لی )has servants who are neither Prophets nor Martyrs and whom the Prophets and Martyrs yearn to be like, due to their seat and proximity in relation to Allah ( سبحانہ و تعا لی )". One of the Bedouin Arabs who came from among the most isolated of people twisted his hand and said-"O' Messenger of Allah (صلى الله عليه و آله وسلم) ! people from human kind who are neither Prophets, nor Martyrs and yet the Prophets and martyrs yearn to be like them due to their seat and proximity in relation to Allah( سبحانہ و تعا لی ) Describe them for us"

'The Prophet's (صلى الله عليه و آله وسلم) face showed delight at the Bedouin's question and he said - " They are of the strangers from this and that place. They frequent this or that tribe without belonging to them. They do not have family connections among themselves. They love one another for Allah's ( سبحانہ و تعا لی ) sake. They are of pure intent towards one another. On the Day of Resurrection, Allah ( سبحانہ و تعا لی )will place for them pedestals of light upon which He will make them sit, and He will turn their faces and clothes into light. On the Day of Resurrection the people will be terrified but not those. They are Allah's ( سبحانہ و تعا لی ) friends (Awliya Allah) upon whom fear comes not, nor do they grieve".
The above Hadith is related through several chains by Abu Dawud, Ahmad. Baghawi in Sharh al-Sunna, al-Hakim in the Mustadrak, Ibn 'Asakir, Ibn Abi al-Dunya in Kitab al-Ikhwan, Ibn Jarir al-Tabari, Ibn Abi Hatim, Ibn Mardawayh,and others. Haythami in Majma'al-Zawa'id says: 'Ahmadrelates it, and Tabrani relates something similar, and all the men in its chain of transmission have been declared trustworthy" .

(16) It is in Quran - "Behold the friends of Allah( سبحانہ و تعا لی )! On them shall come no fear, nor shall they grieve. These are they, who have believed in Allah ( سبحانہ و تعا لی ) and are mindful of (close to) Him and (have consequently abstained from everything evil). To them tidings come (from Allah - سبحانہ و تعا لی ) of a happy life both in this world and in Hereafter. The word of Allah ( سبحانہ و تعا لی ) is never revoked. This in itself is a great felicity (Younus - 62-64).


Building elevated Graves of the important dignitaries of Islam higher from the ground is the practice from the beginning which was continued by Salaf and Khalaf and their followers. It is in Bukhari (refer Hadith No. 1 above) that the sacred grave of the Prophet (صلى الله عليه و آله وسلم) is elevated from the ground.

It is in Quran - وَكَذَ‌ٰلِكَ أَعْثَرْنَا عَلَيْهِمْ لِيَعْلَمُوا أَنَّ وَعْدَ اللَّهِ حَقٌّ وَأَنَّ السَّاعَةَ لَا رَيْبَ فِيهَا إِذْ يَتَنَازَعُونَ بَيْنَهُمْ أَمْرَهُمْ ۖ فَقَالُوا ابْنُوا عَلَيْهِم بُنْيَانًا ۖ رَّبُّهُمْ أَعْلَمُ بِهِمْ ۚ قَالَ الَّذِينَ غَلَبُوا عَلَىٰ أَمْرِهِمْ لَنَتَّخِذَنَّ عَلَيْهِم مَّسْجِدًا [Meaning - Thus did We make their case (As haab-e-Kahaf - Companions of the Cave) known to the people, that they might know that the promise of Allah ( سبحانہ و تعا لی) is true, and that there can be no doubt about the Hour of Judgment. Behold, they (the people) dispute among themselves as to their affair. (Some) said, "Construct a building over them". Their Lord knows best about them (the companions of the cave). Those who prevailed over their affair said, "Let us surely build a mosque over them."] (Al-Kahaf - 21).

The above Quranic verse confirms the fact that even mosques can be build over the pious graves of Awliya Allah. The graves will be on a side and the Masjid can be used for congregational prayers of Muslims. Masjid-e-Nabawi ( صلى الله عليه و آله وسلم ) is the great example in this context. As a matter of fact every Mazaar of Awliya Allah in the world has a mosque adjacent or attached with it.

It is in "Fatawa Shaami", Vol. 1: "If the deceased is from amongst the Masha'aikh (Great Predecessors), Ulema (Islamic Scholars) and Sayeds (descendants of the Holy Prophet - صلى الله عليه و آله وسلم ) then to erect a Mausoleum upon their graves is desirable."

Salaf and Khalf who built grills, domes and structures, mosques over the graves of prominent personalities of Islam were absolutely right in their actions because they wanted to keep the memorials of these personalities intact for the following generations of Muslims (till the day of resurrection) so that they can visit these places and benefit from tabarruk and tawassul.
