It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) entered a garden of Banu Najjar. There, he heard the voices of some people who had died during the time of ignorance and were being punished in their graves. The Prophet (peace and blessings be upon him) became anxious and left from there, and he instructed the companions to seek refuge from the punishment of the grave.
