Malik related to me from Abdullah ibn Abi Bakr ibn Hazm that hisfather told him that he was sitting with Aban ibn Uthman, and anargument was brought to him between some people from the Juhayna tribeand some people from the Banu al-Harith ibn al-Khazraj. A woman of theJuhayna tribe was married to a man from the Banu al-Harith ibn al-Khazraj, called Ibrahim ibn Kulayb. She died and left property andmawali, and her son and husband inherited them from her. Then her sondied and his heirs said, "We have the wala' of the mawali. Her sonobtained them." Those of the Juhayna said, "It is not like that. Theyare the mawali of our female associate. When her child died, we havetheir wala' and we inherit them." Aban ibn Uthman gave a judgementthat the people from the Juhayna tribe did indeed have the wala' ofthe mawali.
