The prohibition of selling fresh dates in exchange for dry dates except in the case of 'Araya
Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ زَيْدِ، بْنِ ثَابِتٍ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ لِصَاحِبِ الْعَرِيَّةِ أَنْ يَبِيعَهَا بِخَرْصِهَا مِنَ التَّمْرِ .
Zaid b. Thabit (Allah be pleased with him) reported Allah's Messenger (may peace he upon him) having given concession in case of 'ariyya for selling dry dates (with) fresh dates after measuring them out.
