﴿ يَخْتَصُّ بِرَحْمَتِهِۦ مَن يَشَآءُ ۗ وَٱللَّهُ ذُو ٱلْفَضْلِ ٱلْعَظِيمِ ﴾

“singling out for His grace whom He wills. And God is limitless in His great bounty."”

(He selecteth for His mercy) He chooses for His religion (whom He will) Muhammad and his Companions. (Allah is of Infinite Bounty) He is generous towards Muhammad by bestowing upon him prophethood and Islam.
