I said to Tawus, "I wish you would give up Mukhabara (Sharecropping), for the people say that the
Prophet forbade it." On that Tawus replied, "O `Amr! I give the land to sharecroppers and help them.
No doubt; the most learned man, namely Ibn `Abbas told me that the Prophet (ﷺ) had not forbidden it but
said, 'It is more beneficial for one to give his land free to one's brother than to charge him a fixed
rental."
