It is narrated from Hazrat Aisha (may Allah be pleased with her) that once the Prophet (peace and blessings be upon him) came to me and a Jewish woman was sitting with me, and she was saying, "Do you know that you will be tested in your graves?" The Prophet (peace and blessings be upon him) turned towards us and said, "Only the Jews will be subjected to trial." After some time had passed, one day the Prophet (peace and blessings be upon him) said to me, "Did you know that revelation has come to me that you will be tested in your graves?" After that, I always heard the Prophet (peace and blessings be upon him) seeking refuge from the punishment of the grave.
