Narrated Ibn `Umar: The Prophet stood at the well of Badr (which contained the corpses of the pagans) and said, "Have you found true what your lord promised you?" Then he further said, "They now hear what I say." This was mentioned before `Aisha and she said, "But the Prophet said, 'Now they know very well that what I used to tell them was the truth.' Then she recited (the Holy Verse):-- "You cannot make the dead hear... ...till the end of Verse)." (30.52)

Narrated Ibn `Umar: The Prophet looked at the people of the well (the well in which the bodies of the pagans killed in the Battle of Badr were thrown) and said, "Have you found true what your Lord promised you?" Somebody said to him, "You are addressing dead people." He replied, "You do not hear better than they but they cannot reply."

Narrated `Aisha: The Prophet said, "They now realize that what I used to tell them was the truth. "And Allah said, 'Verily! You cannot make the dead to hear (i.e. benefit them, and similarly the disbelievers) nor can you make the deaf hear. (27.80).
