"The Messenger of Allah ﷺ forbade the Muzabanah. The Muzdbanah means when a man sells the dates of his grove when they are still on the tree, for a measure of dty dates;[2] or, if it is grapes, he sells them when they are still on the vine, for a measure of raisins; or if it is a crop, he sells it for food, estimating the amount (of the crop in the field). He forbade all of these things."
نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْمُزَابَنَةِ وَالْمُزَابَنَةُ أَنْ يَبِيعَ الرَّجُلُ تَمْرَ حَائِطِهِ إِنْ كَانَتْ نَخْلاً بِتَمْرٍ كَيْلاً وَإِنْ كَانَتْ كَرْمًا أَنْ يَبِيعَهُ بِزَبِيبٍ كَيْلاً وَإِنْ كَانَتْ زَرْعًا أَنْ يَبِيعَهُ بِكَيْلِ طَعَامٍ نَهَى عَنْ ذَلِكَ كُلِّهِ
