Sunan ad-Darimi

It is narrated from Abu Bakr bin Amr bin Hazm that a woman from Banu Muharib gifted the wala’ (right of inheritance) of her slave to the same (slave) and set him free. That slave then gave his wala’ (right of inheritance) to Abdur Rahman bin Amr bin Hazm. Later, when the woman died, the freed slave’s mawali (clients) filed a case before Sayyiduna Uthman (may Allah be pleased with him). Sayyiduna Uthman (may Allah be pleased with him) asked for proof of his statement. The slave brought the proof, so he (Uthman) decided: “Go, and appoint whomever you wish as your wali (patron).” Thus, he appointed Abdur Rahman bin Amr bin Hazm as his wali, that is, as the inheritor of the wala’.
