Sahih Muslim 586 a
'A'isha reported:
There came to me two old women from the old Jewesses of Medina and said: The people of the grave are tormented in their graves. I contradicted them and I did not deem it proper to testify them. They went away and the Messenger of Allah (ﷺ) came to me and I said to him: Messenger of Allah I there came to me two old women from the old Jewesses of Medina and asserted that the people of the graves would be tormented therein. He (the Prophet) said: They told the truth; they would be tormented (so much) that the animals would listen to it. She ('A'isha) said: Never did I see him (the Holy Prophet) afterwards but seeking refuge from the torment of the grave in prayer.
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، كِلاَهُمَا عَنْ جَرِيرٍ، قَالَ زُهَيْرٌ حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَتْ عَلَىَّ عَجُوزَانِ مِنْ عُجُزِ يَهُودِ الْمَدِينَةِ فَقَالَتَا إِنَّ أَهْلَ الْقُبُورِ يُعَذَّبُونَ فِي قُبُورِهِمْ ‏.‏ قَالَتْ فَكَذَّبْتُهُمَا وَلَمْ أُنْعِمْ أَنْ أُصَدِّقَهُمَا فَخَرَجَتَا وَدَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقُلْتُ لَهُ يَا رَسُولَ اللَّهِ إِنَّ عَجُوزَيْنِ مِنْ عُجُزِ يَهُودِ الْمَدِينَةِ دَخَلَتَا عَلَىَّ فَزَعَمَتَا أَنَّ أَهْلَ الْقُبُورِ يُعَذَّبُونَ فِي قُبُورِهِمْ فَقَالَ ‏
"‏ صَدَقَتَا إِنَّهُمْ يُعَذَّبُونَ عَذَابًا تَسْمَعُهُ الْبَهَائِمُ ‏"‏ ‏.‏ قَالَتْ فَمَا رَأَيْتُهُ بَعْدُ فِي صَلاَةٍ إِلاَّ يَتَعَوَّذُ مِنْ عَذَابِ الْقَبْرِ ‏.‏
