Muhammad Bin Yahya, from Ahmad Bin Muhammad and Ali Bin Ibrahim, from his father, both together from Ibn Mahboub, from Abu Wallad Al Hannat who said, ‘I asked Abu Abdullah asws about a contracted slave, his master stipulated a condition upon him when he contracted him, he would pay to a man he commits a crime against. So he asws said; ‘If he has fulfilled something from his contract, he would be fined for his crime in accordance with what he has paid from his contract, to the free. So if he was frustrated from (paying) anything from the right of the crime, that would be taken from the wealth of the master who had contracted him’. I said, ‘If it was that the (compensation of the) crime was for the slave?’ So he asws said: ‘A similar amount would be handed over to the master of the slave whom the contracted slave injured, and there would be no retaliation between the contracted slave and the (owned) slave when it was that the contracted slave had paid something off from his contract. So if he did not happen to have paid something off from his contract, so the slave would be retaliated from him, or the master would be fined for every crime which the contracted slave committed, because he is his slave, if he has not paid anything off from his contract’.

Ibn Mahboub, from Abu Ayoub, from Muhammad Bin Muslim who said, ‘I asked Abu Ja’far asws about a contracted slave who killed a man in error. So he asws said: ‘If it was the case that his master had stipulated upon him when he contracted him, that if he was frustrated (from paying), so he would return it with regards to the slave, so he would be at the status of the owned slave. He would be handed over to the guardians of the killed one, so if they so desire to they can kill him, and if they so desire to they can sell him. And if it was that his master, when he contracted him, did not stipulate upon him, and it was such that he had paid something off from his contract, so Ali asws was saying: ‘He would be free from the contract in proportionate to what he has paid off from his contract’. Thus it would be upon the Imam asws that he asws pays the wergild to the guardians of the killed one in accordance to what he has been freed from the contract, and the blood of a Muslim person would not be invalidated. And I asws see that whatever remains upon the contracted slave, from what he has not paid off, he would be enslave to the guardians of the killed one, to serve them for his life, in proportionate to what remains upon him, and it would not be for them that they sell him’.

Ali Bin Ibrahim, from his father, from Ismail Bin Marrar, from Yunus, from Abdullah Bin Sinan, (It has been narrated) from Abu Abdullah asws having said regarding a contracted slave who killed a man in error. He asws said: ‘Upon him from his wergild, is in proportion to what he is free, and upon his master is what remains from the value of the price. So if the contracted slave is frustrated (from paying), so there is no blood (compensation) for him. But rather, that is upon the Imam asws of the Muslims’.

Ali Bin Ibrahim, from his father, from Al Hassan Bin Mahboub, from Al Hassan Bin Salih, (It has been narrated) from Abu Abdullah asws regarding a free man who kills a slave who value is twenty thousand Dirham. So he asws said: ‘It is not allowed that the value of a slave should be more than the wergild of a free’.
