Sahih Bukhari | Volume 3 | Hadith Number 534
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.'"
