Musannaf Ibn Abi Shaybah 29437 — A man who strikes another man

Hasan bin Muslim said that a slave woman bit the finger of a freed slave of Banu Zayd, and it swelled up, and then that man died. The slave woman also admitted to biting his finger. In this matter, Umar bin Abdul Aziz decided that Banu Zayd would swear fifty oaths, in such a way that the oaths are returned to them, that the man died because of the slave woman's bite; then the slave woman would go to them, otherwise they would have no right. But they refused to swear.
