Sayyiduna Amr bin al-Harith (may Allah be pleased with him) says: By Allah! The Messenger of Allah (peace and blessings be upon him) left behind neither a dirham, nor a dinar, nor a slave, nor a slave-woman, nor anything else, except a white mule, his arms and some land, and that too was given in charity.
