Mujahid said to Tiwus: Come along with me to Ibn Rafi b. Khadij in order to listen from him the hadith transmitted on the authority of his father (pertaining to the renting of land) from Allah's Apostle (may peace be upon him). He (Tawus) scolded him and said: By Allah, it I were to know that Allah's Messenger (may peace be upon him) had forbidden it, I would have never done it. But it has been narrated to me by one who has better knowledge of it amongst them (and he meant Ibn 'Abbas) that Allah's Messenger (may peace be upon him) said: It is better if a person lends, his land to his brother (for cultivation) than that he gets recognised rent on it.
