(An-Naml) 27 : 81
وَمَا أَنْتَ بِهَادِي الْعُمْيِ عَنْ ضَلَالَتِهِمْ ۖ إِنْ تُسْمِعُ إِلَّا مَنْ يُؤْمِنُ بِآيَاتِنَا فَهُمْ مُسْلِمُونَ
And you can’t guide the blind away from their astray; you will only make hear those who believe in Our verses and are Muslims.
Blind mentioned in the verse is not about blind men, instead, it is about those who don’t utilize Adhikr which is the Food, Cloth, and Sight of the human soul as explained in verse 7: 26. See explanation 16: 102; 25: 33-34; 27: 75 and 30: 52-53.
