Musannaf Ibn Abi Shaybah 22383 — A slave shared by two men, one

Al-Hasan said concerning a slave jointly owned by two men that it is disliked to make him a mukatab without the permission of the other partner. If he makes him a mukatab without permission, then whatever the first partner collects from the slave, he is to divide with the other partner. Then, when the slave has paid the full contract price, he becomes free, and he is to work to earn half of his value for the master who did not make him a mukatab, and the slave's wala' (right of clientage) goes to them both.
