It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) was going to the gardens of Hazrat Abu Talha (may Allah be pleased with him) to relieve himself. Hazrat Bilal (may Allah be pleased with him) was walking behind the Prophet (peace and blessings be upon him), and he considered it disrespectful to walk beside the Prophet (peace and blessings be upon him). While walking, the Prophet (peace and blessings be upon him) passed by a grave and stood there until Hazrat Bilal (may Allah be pleased with him) also arrived. The Prophet (peace and blessings be upon him) said, "O Bilal! Do you also hear the sound that I am hearing?" He replied, "I do not hear any sound." The Prophet (peace and blessings be upon him) said, "The one in this grave is being punished." Upon inquiry, it was found out that he was a Jew.
