‘Ubayah bin Rifa’ah narrates that when his grandfather passed away, he left behind a slave girl, an animal for irrigating the fields, a slave who did cupping, and some land. The Messenger of Allah (peace and blessings be upon him) forbade taking earnings from the slave girl out of fear that she might start committing adultery. Regarding the slave, he said: Whatever the cupper earns, feed it to the irrigation animal such as a camel, etc. And regarding the land, he said: Either cultivate it yourself or leave it.
