Al-Qasas 56

إِنَّكَ لَا تَهْدِى مَنْ أَحْبَبْتَ وَلَـٰكِنَّ ٱللَّهَ يَهْدِى مَن يَشَآءُ ۚ وَهُوَ أَعْلَمُ بِٱلْمُهْتَدِينَ

innaka lā tahdī man aḥbabta walākinna l-laha yahdī man yashāu wahuwa aʿlamu bil-muh'tadīna

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.
