الشرح المختصر :

"Qinn" (full slave) is one of two categories of slaves: 1. A slave who is in full slavery. Such a slave is called "qinn", whether he is possessed by one master or is jointly possessed by a number of masters. 2. A slave who is not in full slavery, such as the slave of whom part, like a half or a fourth, has been emancipated while the rest remains in slavery; or the slave who has means of emancipation. Such a slave is of three types: 1. "Umm al-walad" (a child's mother): this is a slave girl who gives birth to a child from her master. Thereby, she becomes entitled to freedom upon the death of her master. 2. "Mukātab": a slave who has bought himself from his master in return for a price to be paid in installments. Freedom becomes due to such a slave once he has paid the full price. 3. "Mudabbar": a slave whose master has decided that he shall be free once he dies. In other words, the "mudabbar" is a slave whose emancipation is determined in a will or is conditional on a certain state or date. In these preceding types, possession is complete. In case of a bondwoman, for example, her master may still have sexual intercourse with her, however, it is the slavery that has become partial, given the existence of a cause of freedom.
