Rafi (RA) reported that Zuhair bin Rafi (who was his uncle) came to me and said: Allah's Messenger (ﷺ) forbade a practice which was useful for us. I said: What is this? (I believe) that whatrver Allah's Messenger (ﷺ) says is absolutely true. He (Zuhair) said that he (the Holy Prophet) asked me: What do you do with your cultivable lands? I said: Allah's Messenger, we rent those irrigated by canals for dry dates or barley. He said: Don't do that. Cultivate them or let them be cultivated (by others) or retain them yourself.
Thauban, the freed slave of Allah's Messenger (ﷺ) , reported: Allah's Messenger (ﷺ) said to me on the occasion of Hajjat-al-Wada' (the Farewell Pilgrimage): Make the flesh usable. So I made it usable (for him) and he ate it constantly until he reached Madinah.
