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 ( صلی اللہ علیہ وسلم ). He (Tawus) scolded him and said: By Allah, it I were to know that Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ) said: It is better if a person lends, his land to his brother (for cultivation) than that he gets recognised rent on it.
Tawus reported that he let out his land on rent, whereupon Amr said: I said to him: Abu Abd al-Rahrman, I wish if you abandon this renting of land, for they alleged that Allah's Apostle ( صلی اللہ علیہ وسلم ) forbade Mukhabara. He siad: Amr, one who has informed me has the best knowledge of it among them (he meant Ibn Abbas). (He said) that Allah's Apostle ( صلی اللہ علیہ وسلم ) did not prohibit it altogether, but said: Lending of land by one among you to his brother is better for him than getting a specified amount of produce from it.
