A mukatab slave who brings all his contract payments at once

It is narrated from Muhammad (Ibn Sirin) that a mukatab slave wanted to pay his entire contract sum at once, but his master said: "I will only take it in instalments (little by little)." Sayyiduna Uthman (may Allah be pleased with him) ordered the slave's emancipation, took the money from him and kept it, and said: "I will keep paying it out little by little." When the master saw this situation, he took the whole of the money at once.

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.

It is narrated from Abu Bakr bin Amr bin Hazm that a man made his slave a mukatab and stipulated that he pay the contract sum in instalments. The mukatab came with his entire contract sum, but his master refused to receive it all at once. The mukatab came to Sayyiduna Umar (may Allah be pleased with him), who sent for his master. When he came, he offered him all that money, but he refused to accept it. Sayyiduna Umar said: "O Yarfa', put this money in the public treasury (Bayt al-Mal)." And he said to the master: "Keep collecting it from the public treasury in instalments." And he said to the slave: "Go, you are free."
