We used to cultivate land on rent during the lifetime of Allah's Apostle ﷺ and we got a share out of the grain left in the ears after threshing them and something unspecified. Messenger of Allah ﷺ said: He who has land should cultivate it or let his brother till it, otherwise he should leave it. (Using translation from Muslim 1536s)
كُنَّا نُخَابِرُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فَنُصِيبُ مِنَ الْقَصْرِيِّ وَمِنْ كَذَا فَقَالَ مَنْ كَانَتْ لَهُ أَرْضٌ فَلْيَزْرَعْهَا أَوْ لِيُحْرِثْهَا أَخَاهُ وَإِلَّا فَلْيَدَعْهَا
