Umarah and Bilal, the two sons of Yahya bin Bilal bin al-Harith, narrate through their father from their grandfather, Sayyiduna Bilal bin al-Harith (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) granted him this land grant and had it written for him: "Bismillah al-Rahman al-Rahim (In the name of Allah, the Most Gracious, the Most Merciful). This is what Muhammad, the Messenger of Allah (peace and blessings be upon him), has given to Bilal bin al-Harith: he has given him the mines of al-Qabaliyyah, its lowlands and its highlands, Ghashiyah, Dhat al-Nusub, and those parts of Quds where crops can be grown, if he is truthful." And Mu'awiyah wrote it.
