Sahih al-Bukhari 3980, 3981
Narrated Ibn `Umar:
The Prophet (ﷺ) 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 (ﷺ) 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)
حَدَّثَنِي عُثْمَانُ، حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ وَقَفَ النَّبِيُّ صلى الله عليه وسلم عَلَى قَلِيبِ بَدْرٍ فَقَالَ ‏{‏هَلْ وَجَدْتُمْ مَا وَعَدَ رَبُّكُمْ حَقًّا ثُمَّ قَالَ إِنَّهُمُ الآنَ يَسْمَعُونَ مَا أَقُولُ‏}‏  فَذُكِرَ لِعَائِشَةَ فَقَالَتْ إِنَّمَا قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ إِنَّهُمُ الآنَ لَيَعْلَمُونَ أَنَّ الَّذِي كُنْتُ أَقُولُ لَهُمْ هُوَ الْحَقُّ ‏"‏‏.‏ ثُمَّ قَرَأَتْ ‏{‏إِنَّكَ لاَ تُسْمِعُ الْمَوْتَى‏}‏ حَتَّى قَرَأَتِ الآيَةَ‏.‏
