﴿ إِنَّكَ لَا تَهْدِى مَنْ أَحْبَبْتَ وَلَٰكِنَّ ٱللَّهَ يَهْدِى مَن يَشَآءُ ۚ وَهُوَ أَعْلَمُ بِٱلْمُهْتَدِينَ ﴾

“VERILY, thou canst not guide aright everyone whom thou lovest: but it is God who guides him that wills [to be guided]; and He is fully aware of all who would let themselves be guided.”

(Lo! thou) O Muhammad (guidest not) know not (whom thou lovest) i.e. whom you love to accept faith: i.e. Abu Talib, (but Allah guideth) He gives success and leads (whom He will) to His religion: Abu Bakr, 'Umar and their fellow believers. (And He is best aware of those who walk aright) to His religion.
