I said to Tawus: “O Abu 'Abdur-Rahman, why do you not give up this Mukhabarah because they claim that the Messenger of Allah ﷺ forbade it.” He said: “O 'Amr, I help them by taking their land and cultivating it, and giving them something in return, and Muʿadh bin Jabal allowed people here to do that. The most knowledgeable of them - meaning IbnʿAbbas - told me that the Messenger of Allah ﷺ did not forbid it, rather he said: 'For one you to give (land) to his brother is better than if he were to take a set amount in rent for it.'”
قُلْتُ لِطَاوُسٍ يَا أَبَا عَبْدِ الرَّحْمَنِ لَوْ تَرَكْتَ هَذِهِ الْمُخَابَرَةَ فَإِنَّهُمْ يَزْعُمُونَ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْهُ فَقَالَ أَىْ عَمْرُو إِنِّي أُعِينُهُمْ وَأُعْطِيهِمْ وَإِنَّ مُعَاذَ بْنَ جَبَلٍ أَخَذَ النَّاسَ عَلَيْهَا عِنْدَنَا وَإِنَّ أَعْلَمَهُمْ يَعْنِي ابْنَ عَبَّاسٍ أَخْبَرَنِي أَنَّ رَسُولَ اللَّهِ ﷺ لَمْ يَنْهَ عَنْهَا وَلَكِنْ قَالَ لأَنْ يَمْنَحَ أَحَدُكُمْ أَخَاهُ خَيْرٌ لَهُ مِنْ أَنْ يَأْخُذَ عَلَيْهَا أَجْرًا مَعْلُومًا
