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 ﷺ. He (Tawus) scolded him and said: By Allah, it I were to know that Messenger of Allah ﷺ 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 Messenger of Allah ﷺ said: It is better if a person lends, his land to his brother (for cultivation) than that he gets recognised rent on it.  

عَنِ النَّبِيِّ ﷺ قَالَ فَانْتَهَرَهُ قَالَ إِنِّي وَاللَّهِ لَوْ أَعْلَمُ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْهُ مَا فَعَلْتُهُ وَلَكِنْ حَدَّثَنِي مَنْ هُوَ أَعْلَمُ بِهِ مِنْهُمْ يَعْنِي ابْنَ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لأَنْ يَمْنَحَ الرَّجُلُ أَخَاهُ أَرْضَهُ خَيْرٌ لَهُ مِنْ أَنْ يَأْخُذَ عَلَيْهَا خَرْجًا مَعْلُومًا  

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 ʿAmr! I give the land to sharecroppers and help them. No doubt; the most learned man, namely Ibn ʿAbbas 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." (Using translation from Bukhārī 2330)   

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْهُ قَالَ أَيْ عَمْرُو إِنِّي أُعْطِيهِمْ وَأُعِينُهُمْ وَإِنَّ أَعْلَمَهُمْ أَخْبَرَنِي يَعْنِي ابْنَ عَبَّاسٍ أَنَّ النَّبِيَّ ﷺ لَمْ يَنْهَ عَنْهُ وَلَكِنْ قَالَ أَنْ يَمْنَحَ أَحَدُكُمْ أَخَاهُ خَيْرٌ لَهُ مِنْ أَنْ يَأْخُذَ عَلَيْهَا خَرْجًا مَعْلُومًا
