أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم سَمِعَ صَوْتًا مِنْ قَبْرٍ فَقَالَ ‏"‏ مَتَى مَاتَ هَذَا ‏"‏ ‏.‏ قَالُوا مَاتَ فِي الْجَاهِلِيَّةِ ‏.‏ فَسُرَّ بِذَلِكَ وَقَالَ ‏"‏ لَوْلاَ أَنْ لاَ تَدَافَنُوا لَدَعَوْتُ اللَّهَ أَنْ يُسْمِعَكُمْ عَذَابَ الْقَبْرِ ‏"‏ ‏.‏

It was narrated from Anas that the Prophet heard a sound from a grave and said: "When died this man die?" They said: "he died during the Jahiliyyah." So he was delighted and said: "Were it not that you would not bury one another, I would have prayed to Allah to make you hear the torment of the grave." Translation Not Available
