The historical priority and universality of Ibrahim's monotheism

يَـٰٓأَهْلَ ٱلْكِتَـٰبِ لِمَ تُحَآجُّونَ فِىٓ إِبْرَٰهِيمَ وَمَآ أُنزِلَتِ ٱلتَّوْرَىٰةُ وَٱلْإِنجِيلُ إِلَّا مِنۢ بَعْدِهِۦٓ ۚ أَفَلَا تَعْقِلُونَ

O People of the Scripture, why do you argue about Abraham while the Torah and the Gospel were not revealed until after him? Then will you not reason?
