It was narrated from al-Hasan bin Sa`d, from his father, that Yuhannas and Safiyyah were two of the captives of the khumus. Safiyyah committed zina with one of the men of the khumus and gave birth to a child who was claimed by both the fornicator and Yuhannas. They referred the dispute to ‘Uthman, who referred them to `Ali bin Abi Talib. ‘Ali said:
I shall pass judgement between them as the Messenger of Allah (ﷺ) passed judgement: the child belongs to (the husband) of the women and the fornicator gets nothing. And he gave them fifty lashes each.
