The basis for this is the saying of Allah, the Exalted: "Then contract with them if you know there is goodness in them." And the manifest meaning of the command is obligation. It is narrated that Sirin, the father of Muhammad ibn Sirin, was a slave to Anas ibn Malik and asked him to contract with him, but he refused, so he informed...
