It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) went to a deserted place of Banu Najjar in Madinah Munawwarah, where the Prophet (peace and blessings be upon him) used to go to relieve himself. After a short while, the Prophet (peace and blessings be upon him) came to us in a state of anxiety and said, "If you people did not stop burying your dead, I would have prayed to Allah that He let you hear the punishment of the grave."
