Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) passed by us while we were digging a grave. He (peace and blessings be upon him) asked: "What are you doing?" We said: "We are digging a grave for this black man." So he (peace and blessings be upon him) said: "His death has brought him to his soil." Abu Usamah (may Allah have mercy on him) said: "O people of Kufah, do you know why I narrated this hadith to you? Because Abu Bakr and Umar (may Allah be pleased with them both) were created from the soil of the Messenger of Allah (peace and blessings be upon him)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Abu al-Darda' (may Allah be pleased with him) only with this chain; Abu Usamah is alone in narrating it."
