Sahih Bukhari Volume 3, Book 41, Hadith 2343

حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، قَالَ ذَكَرْتُهُ لِطَاوُسٍ فَقَالَ يُزْرِعُ، قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ إِنَّ النَّبِيَّ صلى الله عليه وسلم لَمْ يَنْهَ عَنْهُ وَلَكِنْ قَالَ ‏"‏ أَنْ يَمْنَحَ أَحَدُكُمْ أَخَاهُ خَيْرٌ لَهُ مِنْ أَنْ يَأْخُذَ شَيْئًا مَعْلُومًا ‏"‏‏.‏

Narrated By 'Amr : When I mentioned it (i.e. the narration of Rafi 'bin Khadij: no. 532) to Tawus, he said, "It is permissible to rent the land for cultivation, for Ibn 'Abbas said, 'The Prophet did not forbid that, but said: One had better give the land to one's brother gratis rather than charge a certain amount for it.'"
