Sahih al-Bukhari, Hadith 2330 ⓘ

Narrated `Amr: 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 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."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ عَمْرٌو قُلْتُ لِطَاوُسٍ لَوْ تَرَكْتَ الْمُخَابَرَةَ فَإِنَّهُمْ يَزْعُمُونَ أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنْهُ‏.‏ قَالَ أَىْ عَمْرُو، إِنِّي أُعْطِيهِمْ وَأُغْنِيهِمْ، وَإِنَّ أَعْلَمَهُمْ أَخْبَرَنِي ـ يَعْنِي ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم لَمْ يَنْهَ عَنْهُ، وَلَكِنْ قَالَ ‏ "‏ أَنْ يَمْنَحَ أَحَدُكُمْ أَخَاهُ خَيْرٌ لَهُ مِنْ أَنْ يَأْخُذَ عَلَيْهِ خَرْجًا مَعْلُومًا ‏" ‏‏.‏
