﴿ مَا كَانَ إِبْرَٰهِيمُ يَهُودِيًّۭا وَلَا نَصْرَانِيًّۭا وَلَٰكِن كَانَ حَنِيفًۭا مُّسْلِمًۭا وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ ﴾

“Abraham was neither a "Jew" nor a "Christian", but was one who turned away from all that is false, having surrendered himself unto God; and he was not of those who ascribe divinity to aught beside Him.”

God in order to dissociate Abraham from their claims said No; Abraham in truth was not a Jew neither a Christian but he was a Muslim professing the Oneness of God and a hanīf who inclined away from all other religions towards the upright one; and he was never of the idolaters.
