Musannaf Ibn Abi Shaybah 33778 — Those who permitted giving wala

Abu Bakr bin Amr bin Hazm said that a woman of the tribe of Muharib gifted the wala' of her slave to the slave himself, and she freed him, and he freed himself. He said: Then he gifted his wala' to Abd al-Rahman bin Amr bin Hazm. The woman died, and the mawali brought the case before Sayyiduna Uthman (may Allah be pleased with him). Uthman asked for proof of this, and he brought the proof. Then Uthman said: Go, and form a tie of wala' with whomever you wish. Abu Bakr said: So he formed a tie of muwalat with Abd al-Rahman bin Amr bin Hazm.
