Silsilat al-Ahadith al-Sahihah

Sayyiduna Ubayd bin Rifa’ah bin Rafi’ bin Khadij says: When my grandfather passed away, he left behind a slave woman, a camel, a slave, a barber, and some land. The Messenger of Allah (peace and blessings be upon him) forbade (us from taking) the earnings of the slave woman. Imam Shu’bah says: (It was forbidden) due to the risk of immorality. And the Prophet (peace and blessings be upon him) further said: “Make the barber’s earnings fodder for the camels.” And regarding the land, he said: “Either cultivate it yourself or leave it as it is.”

It is narrated from Sayyiduna Rafi‘ bin Khadij (may Allah be pleased with him), he says: The Messenger of Allah (peace and blessings of Allah be upon him) forbade Muhaqalah and Muzabanah and said: "There are three types of people who cultivate land: ① The man who cultivates crops in his own land, ② The man to whom land has been temporarily gifted, he cultivates crops in it, and ③ The man who has rented land in exchange for gold or silver (he cultivates crops in it)."
