Chapter: Selling of mixed dates
Narrated Abu Sa`id:We used to be given mixed dates (from the booty) and used to sell (barter) two Sas of those dates) for one Sa (of good dates). The Prophet (ﷺ) said (to us), "No (bartering of) two Sas for one Sa nor two Dirhams for one Dirham is permissible", (as that is a kind of usury). (See Hadith No. 405).

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ ـ رضى الله عنه ـ قَالَ كُنَّا نُرْزَقُ تَمْرَ الْجَمْعِ، وَهْوَ الْخِلْطُ مِنَ التَّمْرِ، وَكُنَّا نَبِيعُ صَاعَيْنِ بِصَاعٍ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ صَاعَيْنِ بِصَاعٍ، وَلاَ دِرْهَمَيْنِ بِدِرْهَمٍ ".
