Malik related to me from Abdullah ibn Abi Bakr ibn Muhammad ibnAmr ibn Hazm from Abd al-Malik ibn Abi Bakr ibn Abd ar-Rahman ibn al-Harith ibn Hisham that his father told him that al-Asi ibn Hisham haddied and left three sons, two by one wife and one by another wife. Oneof the two with the same mother died and left property and mawali. Hisfull brother inherited his property and the wala' of his mawali. Thenhe also died, and left as heirs his son and his paternal half brother.His son said, "I obtain what my father inherited of property and thewala' of the mawali." His brother said, "It is not like that. Youobtain the property. As for the wala' of the mawali, it is not so. Doyou think that had it been my first brother who died today, I wouldnot have inherited from him?" They argued and went to Uthman ibnAffan. He gave a judgement that the brother had the wala' of themawali.
