Sahih Muslim , Book 10, Hadith 3719 (USC-MSA)

Jabir (Allah be pleased with him) reported Allah's Messenger as saying: He who has land should cultivate it, but if he does not find it possible to cultivate it, or finds himself helpless to do so, he should lend it to his Muslim brother, but he should not accept rent from him.

حَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا عَبْدُ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ كَانَتْ لَهُ أَرْضٌ فَلْيَزْرَعْهَا فَإِنْ لَمْ يَسْتَطِعْ أَنْ يَزْرَعَهَا وَعَجَزَ عَنْهَا فَلْيَمْنَحْهَا أَخَاهُ الْمُسْلِمَ وَلاَ يُؤَاجِرْهَا إِيَّاهُ ‏" ‏ ‏.‏
