The Holy Quran says: What you have concealed we shall again reveal.
This is a reference to the Pure Knowledge that had been sent to all nations. The Jews in particular are charged with knowingly corrupting and/or disregarding that knowledge for self-gain - the widespread acceptance and application of usuary for example.

Ishmael, "God hears", is the name given to a son born to Abraham's handmaiden. In his impatience to produce a nation in his advanced years, being impatient with God, Abraham created this lad with his personal servant.
By Israeli law Ishmael was the firstborn, but was overlooked. An accident. A mistake. A misjudgement by father Abraham.
So this "red-headed step-child" became a father of a great nation of people, too many to number, as blessed by his father Abraham.
The lost recognition and back-handed blessing has continued to boil for 4,000 years, from Ishmael's birth in B.C. 1908.
