Sahih Bukhari Volume 8, Book 80, Hadith 6368

حَدَّثَنى عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَتْ عَلَىَّ عَجُوزَانِ مِنْ عُجُزِ يَهُودِ الْمَدِينَةِ فَقَالَتَا لِي إِنَّ أَهْلَ الْقُبُورِ يُعَذَّبُونَ فِي قُبُورِهِمْ، فَكَذَّبْتُهُمَا، وَلَمْ أُنْعِمْ أَنْ أُصَدِّقَهُمَا، فَخَرَجَتَا وَدَخَلَ عَلَىَّ النَّبِيُّ صلى الله عليه وسلم فَقُلْتُ لَهُ يَا رَسُولَ اللَّهِ إِنَّ عَجُوزَيْنِ وَذَكَرْتُ لَهُ، فَقَالَ ‏"‏ صَدَقَتَا، إِنَّهُمْ يُعَذَّبُونَ عَذَابًا تَسْمَعُهُ الْبَهَائِمُ كُلُّهَا ‏"‏‏.‏ فَمَا رَأَيْتُهُ بَعْدُ فِي صَلاَةٍ إِلاَّ تَعَوَّذَ مِنْ عَذَابِ الْقَبْرِ‏

Narrated By 'Aisha : Two old ladies from among the Jewish ladies entered upon me and said' "The dead are punished in their graves," but I thought they were telling a lie and did not believe them in the beginning. When they went away and the Prophet entered upon me, I said, "O Allah's Apostle! Two old ladies..." and told him the whole story. He said, "They told the truth; the dead are really punished, to the extent that all the animals hear (the sound resulting from) their punishment." Since then I always saw him seeking refuge with Allah from the punishment of the grave in his prayers.
