Yusuf - 12:38

وَاتَّبَعْتُ مِلَّةَ آبَآئِـي إِبْرَاهِيمَ وَإِسْحَاقَ وَيَعْقُوبَ مَا كَانَ لَنَا أَن نُّشْرِكَ بِاللّهِ مِن شَيْءٍ ذَلِكَ مِن فَضْلِ اللّهِ عَلَيْنَا وَعَلَى النَّاسِ وَلَـكِنَّ أَكْثَرَ النَّاسِ لاَ يَشْكُرُونَ
[12:38]
And I follow the religion of my fathers, Ibrahim and Ishaq and Yaqoub; it beseems us not that we should associate aught with Allah; this is by Allah's grace upon us and on mankind, but most people do not give thanks:
"And I follow the ways of my fathers,- Abraham, Isaac, and Jacob; and never could we attribute any partners whatever to Allah: that (comes) of the grace of Allah to us and to mankind: yet most men are not grateful.
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.
