وَٱتَّبَعْتُ مِلَّةَ ءَابَآءِىٓ إِبْرَٰهِيمَ وَإِسْحَٰقَ وَيَعْقُوبَ ۚ مَا كَانَ لَنَآ أَن نُّشْرِكَ بِٱللَّهِ مِن شَىْءٍۢ ۚ ذَٰلِكَ مِن فَضْلِ ٱللَّهِ عَلَيْنَا وَعَلَى ٱلنَّاسِ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَشْكُرُونَ
And I have followed the religion of my fathers, Abraham and Isaac and Jacob. It never was for us to attribute aught as partner to Allah. This is of the bounty of Allah unto us (the seed of Abraham) and unto mankind; but most men give not thanks.
Surah Yusuf(12:38)
