Sahih Bukhari Volume 3, Book 41, Hadith 2340

حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا الأَوْزَاعِيُّ، عَنْ أَبِي النَّجَاشِيِّ، مَوْلَى رَافِعِ بْنِ خَدِيجٍ سَمِعْتُ رَافِعَ بْنَ خَدِيجِ بْنِ رَافِعٍ، عَنْ عَمِّهِ، ظُهَيْرِ بْنِ رَافِعٍ قَالَ ظُهَيْرٌ لَقَدْ نَهَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَمْرٍ كَانَ بِنَا رَافِقًا‏.‏ قُلْتُ مَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَهْوَ حَقٌّ‏.‏ قَالَ دَعَانِي رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَا تَصْنَعُونَ بِمَحَاقِلِكُمْ ‏"‏‏.‏ قُلْتُ نُؤَاجِرُهَا عَلَى الرُّبُعِ وَعَلَى الأَوْسُقِ مِنَ التَّمْرِ وَالشَّعِيرِ‏.‏ قَالَ ‏"‏ لا تَفْعَلُوا ازْرَعُوهَا أَوْ أَزْرِعُوهَا أَوْ أَمْسِكُوهَا ‏"‏‏.‏ قَالَ رَافِعٌ قُلْتُ سَمْعًا وَطَاعَةً‏.

Narrated By Rafi bin Khadij : My uncle Zuhair said, "Allah's Apostle forbade us to do a thing which was a source of help to us." I said, "Whatever Allah's Apostle said was right." He said, "Allah's Apostle sent for me and asked, 'What are you doing with your farms?' I replied, 'We give our farms on rent on the basis that we get the yield produced at the banks of the water streams (rivers) for the rent, or rent it for some Wasqs of barley and dates.' Allah's Apostle said, 'Do not do so, but cultivate (the land) yourselves or let it be cultivated by others gratis, or keep it uncultivated.' I said, 'We hear and obey.'
