Narrated Ibn 'Umar:
The Prophet ﷺ forbade the sale of fruits on the tree for fruits by measure, and sale of grapes for raisins by measure, and sale of harvest for wheat by measure.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا ابْنُ أَبِي زَائِدَةَ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعِ الثَّمَرِ بِالتَّمْرِ كَيْلاً وَعَنْ بَيْعِ الْعِنَبِ بِالزَّبِيبِ كَيْلاً وَعَنْ بَيْعِ الزَّرْعِ بِالْحِنْطَةِ كَيْلاً .
