It is narrated from Sayyiduna Amr bin al-Harith (may Allah be pleased with him), who was a relative by marriage of the Messenger of Allah (peace and blessings be upon him), namely the brother of his wife Sayyidah Juwayriyah bint al-Harith (may Allah be pleased with her), that he said: "By Allah, at the time of his death the Messenger of Allah (peace and blessings be upon him) left neither a dirham nor a dinar, neither a male slave nor a female slave, nor anything else, except his white mule, his weapons, and a piece of land which he had given in charity."
