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 Allāh].
The Disbelievers are like the Dead, Deaf and Blind
Allah says, `just as you are not able to make the dead hear in their graves, or to make your words reach the deaf who cannot hear and who still turn away from you, so too you cannot guide the blind to the truth and bring them back from their misguidance.' That is a matter which rests with Allah, for by His power He can make the dead hear the voices of the living if He wills. He guides whom He wills and sends astray whom He wills, and no one but He has the power to do this. Allah says:
(you can make to hear only those who believe in Our Ayat, and have submitted (to Allah in Islam).) means, those who are humble and who respond and obey. These are the ones who will listen to the truth and follow it; this is the state of the believers; the former (being deaf and blind) is the state of the disbelievers, as Allah says:
فَإِنَّكَ لَا تُسْمِعُ الْمَوْتَىٰ (So you cannot make the dead to hear 30:52). As for the issue whether the dead have the ability to hear or not, and if they have this ability, whether it is exclusive to some, or all can hear, this subject has been dealt with briefly in the commentary of Sarah An-Naml in this volume, and a detailed discussion can be seen in my book تکمیل الحبور بسماع اھل القبور .
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 53–56
When a man treads the path of Truth, he has frequently to face great difficulties, as happened with the Prophet and his companions in the early days. But, in that case, there was no question of anybody being disappointed. God is so merciful that, when a field under cultivation needs water, He moves the universal system and waters it. Naturally, He will certainly help those who tread His path. However, this help will be forthcoming only according to God’s plan. So, if there is some delay in the process, man should not be disappointed or disheartened. The word of God is very clear and reasonable. But only those who study things in depth, who listen carefully, whose nature it is to accept things that address their mind, who adopt the path which they find to be right, will repose their faith in the word of God.
