Sayyidina Rafi’ ibn Khadij (RA) reported that Allah’s Messenger (SAW) forbade them from something that was profitable to them. When one of them had a piece of land he would let it out against part of its Kharaj or some dirhams. He said, “When one of you has a piece of land then he must either give it to his brother to cultivate without asking for a return or he must cultivate it himself.”
[Bukhari 2339, Muslim 1548]
