Musannaf Ibn Abi Shaybah 21699 — Those who permitted gifting wala

Abu Bakr bin Amr bin Hazm said that a woman from the settlement of Muharib gave her slave's wala' to the slave himself and freed him. The slave then freed himself and gave himself to Abd al-Rahman bin Amr bin Hazm. Then the woman died, and her mawali brought the case before Sayyiduna Uthman bin Affan (may Allah be pleased with him). Sayyiduna Uthman (may Allah be pleased with him) asked for testimony on what he said. He brought the testimony, and Sayyiduna Uthman (may Allah be pleased with him) said to him: Go and establish a wala' tie with whomever you wish. So he established a wala' tie with Abd al-Rahman bin Amr bin Hazm.
