Al-Harith and Bilal narrate from their father Yahya, and he from their grandfather Sayyiduna Bilal bin al-Harith al-Muzani (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) granted him a piece of land as a fief and wrote a document for him: "This is the deed which Muhammad, the Messenger of Allah (peace and blessings be upon him), has granted to Bilal bin al-Harith. He (peace and blessings be upon him) has granted him the mines of al-Qabaliyyah, both their low-lying and their elevated parts, and al-Ghashiyyah, Dhat al-Nusub, and all the places of Quds where cultivation is possible, provided that he works there." And this document was written by Sayyiduna Mu'awiyah (may Allah be pleased with him).
