﴿ وَمَآ أَنتَ بِهَٰدِى ٱلْعُمْىِ عَن ضَلَٰلَتِهِمْ ۖ إِن تُسْمِعُ إِلَّا مَن يُؤْمِنُ بِـَٔايَٰتِنَا فَهُم مُّسْلِمُونَ ﴾

“just as thou canst not lead the blind [of heart] out of their error; none canst thou make hear save such as [are willing to] believe in Our messages, and thus surrender themselves unto Us.”

(Nor canst thou) O Muhammad (lead the blind out of their error) to guidance. (Thou canst make none to hear) your call, (save those who believe Our revelations) Our Scripture and Messenger (and who have surrendered) and are sincere in their worship and profession of Allah's divine Oneness.
