Sahih Muslim , Book 10, Hadith 3684 (USC-MSA) ⓘ
Zaid b. Thabit (Allah be pleased with him) reported Allah's Messenger granting concession in case of 'ariyya transactions and that implies selling of (dry dates for fresh dates) according to a measure.
وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا عُبَيْدُ اللَّهِ، حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، عَنْ زَيْدِ بْنِ ثَابِتٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ فِي الْعَرَايَا أَنْ تُبَاعَ بِخَرْصِهَا كَيْلاً .
