Appeal to reason and rational thought

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?

قَالَ رَبُّ ٱلْمَشْرِقِ وَٱلْمَغْرِبِ وَمَا بَيْنَهُمَآ ۖ إِن كُنتُمْ تَعْقِلُونَ

[Moses] said, "Lord of the east and the west and that between them, if you were to reason."
