He—may Allah have mercy on him—was asked:

About a man who purchased an animal with money that was partly lawful and partly unlawful: what is the ruling of Islamic law?

The answer

He replied:

If he purchased it with money that was partly his own and partly usurped, half of the animal belongs to him, but he has no right to the other half. Rather, he must return that half to its rightful owner if possible; otherwise, he must give it in charity on the owner’s behalf. Any increase arising from it follows the same ruling as the original property: half belongs to him and half to the other party. And Allah knows best.

He was asked:

About a slave woman who requests a zarkash for herself in her mistress’s name, then requests a ring in her mistress’s name. Her mistress denies this, while the slave woman admits it.

He replied:

If she made the request in her mistress’s name without her mistress having authorized her, then the slave woman wrongfully took possession of the item without any right to it. If it is lost or destroyed while in her possession, the claim for compensation attaches to the slave woman’s person. Her mistress has the choice either to redeem her by paying the value of what she took, or to surrender her to be sold, with the compensation taken from the proceeds of her sale. And Allah knows best.
