Al-Muwatta Hadith 39.6

Malik said, "The best of what I have heard about a mukatab who injures a man so that blood-money must be paid, is that if the mukatab can pay the blood-money for the injury with his kitaba, he does so, and it is against his kitaba. If he cannot do that, and he cannot pay his kitaba because he must pay the blood-money of that injury before the kitaba, and he cannot pay the blood-money of that injury, then his master has an option. If he prefers to pay the blood-money of that injury, he does so and keeps his slave and he becomes an owned slave. If he wishes to surrender the slave to the injured, he surrenders him. The master does not have to do more than surrender his slave." Malik spoke about people who were in a general kitaba and one of them caused an injury which entailed blood-money. He said, "If any of them does an injury involving blood-money, he and those who are with him in the kitaba are asked to pay all the blood-money of that injury. If they pay, they are confirmed in their kitaba. If they do not pay, and they are incapable then their master has an option. If he wishes, he can pay all the blood-money of that injury and all the slaves revert to him. If he wishes, he can surrender the one who did the injury alone and all the others revert to being his slaves since they could not pay the blood-money of the injury which their companion caused." Malik said, "The way of doing things about which there is no dispute among us, is that when a mukatab is injured in some way which entails blood-money or one of the mukatab's children who is written with him in the kitaba is injured, their blood-money is the blood-money of slaves of their value, and what is appointed to them as their blood-money is paid to the master who has the kitaba and he reckons that for the mukatab at the end of his kitaba and there is a reduction for the blood-money that the master has taken for the injury." Malik said, "The explanation of that is say, for example, he has written his kitaba for three thousand dirhams and the blood-money taken by the master for his injury is one thousand dirhams. When the mukatab has paid his master two thousand dirhams he is free. If what remains of his kitaba is one thousand dirhams and the blood-money for his injury is one thousand dirhams, he is free straightaway. If the blood-money of the injury is more than what remains of the kitaba, the master of the mukatab takes what remains of his kitaba and frees him. What remains after the payment of the kitaba belongs to the mukatab. One must not pay the mukatab any of the blood-money of his injury in case he might consume it and use it up. If he could not pay his kitaba completely he would then return to his master one eyed, with a hand cut off, or crippled in body. His master only wrote his kitaba against his property and earnings, and he did not write his kitaba so that he would take the blood-money for what happened to his child or to himself and use it up and consume it. One pays the blood-money of injuries to a mukatab and his children who are born in his kitaba, or their kitaba is written, to the master and he takes it into account for him at the end of his kitaba."
