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
