وَمَا أَنتَ بِهَادِي الْعُمْيِ عَن ضَلَلَتِهِمْ
So verily, you cannot make the dead to hear, nor can you make the deaf to hear the call, when they show their backs and turn away.
And you cannot guide the blind from their straying;
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;
إِن تُسْمِعُ إِلاَّ مَن يُوْمِنُ بِأيَاتِنَا فَهُم مُّسْلِمُونَ
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;
إِنَّمَا يَسْتَجِيبُ الَّذِينَ يَسْمَعُونَ وَالْمَوْتَى يَبْعَثُهُمُ اللَّهُ ثُمَّ إِلَيْهِ يُرْجَعُونَ
It is only those who listen will respond, but as for the dead, Allah will raise them up, then to Him they will be returned. (6;36)
A'ishah, the Mother of the faithful, may Allah be pleased with her, used this Ayah --
إِنَّكَ لَا تُسْمِعُ الْمَوْتَى
(So verily, you cannot make the dead to hear), as evidence against Abdullah bin Umar when he reported that the Prophet had addressed the slain disbelievers who had been thrown into a dry well three days after the battle of Badr, rebuking and reprimanding them, until Umar said, "O Messenger of Allah, are you addressing people who are dead bodies?"
He said;
وَالَّذِي نَفْسِي بِيَدِهِ مَا أَنْتُمْ بِأَسْمَعَ لِمَا أَقُولُ مِنْهُمْ وَلَكِنْ لَاا يُجِيبُون
By the One in Whose Hand is my soul, you do not hear what I say any better than they do, but they cannot respond.
A'ishah interpreted this event to mean that the Prophet was making the point that now they would know that what he had been telling them was true.
Qatadah said;
"Allah brought them back to life for him so that they could hear what he said by way of rebuke and vengeance.
