( 139 ) Say, [O Muhammad], "Do you argue with us about Allah while He is our Lord and your Lord? For us are our deeds, and for you are your deeds. And we are sincere [in deed and intention] to Him."
( 140 ) Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allah?" And who is more unjust than one who conceals a testimony he has from Allah? And Allah is not unaware of what you do.


The Holy Quran , surah 2


Abraham was neither a Jew nor a Christian, but he was one inclining toward truth, a Muslim[submitting to Allah]. And he was not of the polytheists.


The Holy Quran 3:67
