And you cannot guide the blind away from their error. You will (30:53)

﴿وَمَا أَنتَ بِهَادِ الْعُمْيِ عَن ضَلَالَتِهِمْ ۖ إِن تُسْمِعُ إِلَّا مَن يُؤْمِنُ بِآيَاتِنَا فَهُم مُّسْلِمُونَ﴾
[ الروم: 53]

30:53 And you cannot guide the blind away from their error. You will only make hear those who believe in Our verses so they are Muslims [in submission to Allah].

You are not able to guide those who have deviated from the straight path, onto treading the right path.
Neither are you able to make anyone hear something beneficial to them, except those who believe in My Verses, because only they are the ones who will benefit from whatever you say; they are the ones submissive and accepting of My command.

And you (O Muhammad SAW) cannot guide the blind from their straying; you can make to hear only those who believe in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), and have submitted to Allah in Islam (as Muslims).
