By "mukatab" is meant a slave who has entered into a contract with his master to purchase his freedom in exchange for a certain sum of money. This contract is called "mukatabah" or "kitabah," and the specified amount is referred to as "maal al-mukatabah." The details have already been discussed previously.

(1) The researcher of the book has declared the chain of narration of this hadith to be weak, but this narration and the subsequent narrations: 4813 and 4814 are also authentic due to supporting and corroborating reports. For the corroboration and supporting evidence of this narration, see hadith: 4815, 4816.
(2) From this hadith, it is understood that a mukatab (a slave who has a contract for his freedom) will be considered free to the extent of the amount he has paid towards his contract, and the remainder will be considered a slave. For example, if a slave has paid half of the agreed amount, he will be half free and half slave. In this state, if he is killed, the blood money (diyah) for the free portion will be fifty camels, and for the remaining slave portion, the blood money will be given as for a slave, i.e., twenty-five camels.
