Surah Al-Qasas — Ayah 56 (28:56)
إِنَّكَ لَا تَهۡدِي مَنۡ أَحۡبَبۡتَ وَلَٰكِنَّ ٱللَّهَ يَهۡدِي مَن يَشَآءُۚ وَهُوَ أَعۡلَمُ بِٱلۡمُهۡتَدِينَ ٥٦
English translation (Saheeh International)
Indeed, [O Muḥammad], you do not guide whom you like, but Allāh guides whom He wills. And He is most knowing of the [rightly] guided.
Brief commentary
O Messenger, you do not guide whomever you love, such as Abu Talib and others, by enabling him to bring faith, but rather Allah alone is the one who enables whomever He wants to be guided. And He knows better regarding whom it has already passed in His knowledge that he will be amongst those guided to the straight path.
