عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَفَعَ إِلَى يَهُودِ خَيْبَرَ نَخْلَ خَيْبَرَ وَأَرْضَهَا عَلَى أَنْ يَعْتَمِلُوهَا مِنْ أَمْوَالِهِمْ وَلِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَطْرُ ثَمَرِهَا. رَوَاهُ مُسْلِمٌ وَفِي رِوَايَةِ الْبُخَارِيِّ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَعْطَى خَيْبَرَ الْيَهُودَ أَنْ يَعْمَلُوهَا ويزرعوها وَلَهُم شطر مَا يخرج مِنْهَا

Rafi‘ b. Khadij said

We had most agricultural land in Medina, and a man would let out his land on condition that he should have what was produced in one portion and the man to whom it was let out should have what was produced in another; but sometimes one portion produced a crop while the other did not, so the Prophet forbade them to do that. (Bukhari and Muslim.)
