Sunan Ibn Majah Book 16, Hadith 2451

حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ الدِّمَشْقِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا الأَوْزَاعِيُّ، حَدَّثَنِي عَطَاءٌ، قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ كَانَتْ لِرِجَالٍ مِنَّا فُضُولُ أَرَضِينَ يُؤَاجِرُونَهَا عَلَى الثُّلُثِ وَالرُّبُعِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ مَنْ كَانَتْ لَهُ فُضُولُ أَرَضِينَ فَلْيَزْرَعْهَا أَوْ لِيُزْرِعْهَا أَخَاهُ فَإِنْ أَبَى فَلْيُمْسِكْ أَرْضَهُ ‏"‏ ‏.‏

Ata' said:“I heard Jabir bin 'Abdullah say: Some men among us had extra land which they would rent out for one third or one quarter (of the crop). The Prophet (ﷺ) said: “Whoever has extra land, let him cultivate it (himself) or let him give it to his brother (for free, to cultivate it), and if he does not want to do that, let him keep his land.”
