Al-Qasas 28:56

You cannot guide whoever you like, but Allah guides whom He wills, and He knows best who will be guided.

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.

56. Verily you (O Muhammad صلى الله عليه وسلم) guide not whom you like, but Allâh guides whom He wills. And He knows best those who are the guided.[3]

[3] (V.28:56) Narrated Al-Musayyab: When Abû Tâlib was on his death bed, the Prophet صلى الله عليه وسلم went to him while Abû Jahl was sitting beside him. The Prophet صلى الله عليه وسلم said: "O my uncle! Say: Lâ ilâha illallâh (none has the right to be worshipped but Allah), an expression with which I will defend your case, before Allah." Abû Jahl and ‘Abdullâh bin Umayyah said: "O Abû Tâlib! Will you leave the religion of ‘Abdul Muttalib?" So they kept on saying this to him so that the last statement he said to them (before he died) was: "I am on the religion of ‘Abdul Muttalib." Then the Prophet صلى الله عليه وسلم said: "I will keep on asking for Allah’s Forgiveness for you unless I am forbidden to do so." Then the following Verse was revealed: "It is not proper for the Prophet and those who believe to ask Allah’s Forgiveness for the Mushrikûn even though they be of kin, after it has become clear to them that they are the dwellers of the (Hell) Fire (because they died in a state of disbelief)." (V.9:113).
The other Verse was also revealed: "Verily, you (O Muhammad صلى الله عليه وسلم) guide not whom you like, but Allah guides whom He wills." (V.28:56). (Sahih Al Bukhari, Vol.5, Hadîth No.223).

Lo! thou (O Muhammad) guidest not whom thou lovest, but Allah guideth whom He will. And He is Best Aware of those who walk aright.
