﴿ 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.”
