Sahih Bukhari Volume 3, Book 41, Hadith 2341

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، أَخْبَرَنَا الأَوْزَاعِيُّ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ ـ رضى الله عنه ـ قَالَ كَانُوا يَزْرَعُونَهَا بِالثُّلُثِ وَالرُّبُعِ وَالنِّصْفِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ مَنْ كَانَتْ لَهُ أَرْضٌ فَلْيَزْرَعْهَا أَوْ لِيَمْنَحْهَا، فَإِنْ لَمْ يَفْعَلْ فَلْيُمْسِكْ أَرْضَهُ ‏"‏‏.‏

Narrated By Jabir : The people used to rent their land for cultivation for one-third, one-fourth or half its yield. The Prophet said, "Whoever has land should cultivate it himself or give it to his (Muslim) brother gratis; otherwise keep it uncultivated."
