Musannaf Ibn Abi Shaybah 24014 — A mukatab slave who brings all

The case was brought before Sayyiduna Umar (may Allah be pleased with him) of a mukatab slave who had brought his whole contract sum at once, but his master said: "I will not accept it all at once. I made him a mukatab only so that I could keep collecting it from him little by little over the years, which would benefit me, and perhaps during that time he may die and I will inherit from him." Sayyiduna Umar ordered that the money be taken from him and placed in the public treasury (Bayt al-Mal), and then paid to his master in instalments, and he ruled that the slave was free.
