It is narrated from Hazrat Anas (may Allah be pleased with him) that some of the companions of the Prophet (peace and blessings be upon him), "whom I do not consider suspect," informed me that one day the Prophet (peace and blessings be upon him) and Hazrat Bilal (may Allah be pleased with him) were walking in Jannat al-Baqi'. The Prophet (peace and blessings be upon him) said, "Bilal! As I am hearing, are you also hearing any sound?" He replied, "O Messenger of Allah (peace and blessings be upon him)! By Allah! I am not hearing any sound." The Prophet (peace and blessings be upon him) said, "Do you not hear that the people of ignorance are being punished in their graves?"
