Musannaf Ibn Abi Shaybah

Hazrat Sufyan narrates that Hazrat Ali (may Allah be pleased with him) bin Aqmar said: I found one of our slaves who was working in a well located in Utbah's house. I presented his case before Hazrat Shurayh, so he said: You must clarify that they had compelled him, otherwise, whomever you wish from the household will take an oath on your behalf.

Hazrat Ibn Jurayj states that Hazrat Ibn Shihab said to me: There is no Qasamah in the case of a slave, nor can Qasamah be returned to him. Indeed, these are oaths, like a right that is claimed.

Hazrat Ibn Jurayj states that Hisham bin Abdul Malik made a judgment of fifty oaths upon Ayyub regarding Ayyub’s slave, the freedman of Ibn Nafi’: so he (Ayyub) took the oath and received its price.
