Musannaf Ibn Abi Shaybah

Hazrat Sha'bi (may Allah have mercy on him) says regarding the person who buys a slave-girl and she runs away from him: if a defect was concealed at the time of sale or he was deceived, then he will return the price and demand his slave-girl back. And Hazrat Shurayh used to say that he will return only that slave-girl.
