Narrated Sahl b. Abi Khathmah:The Messenger of Allah (ﷺ) forbade the sale of fruits for dried dates, but gave license regarding the 'araya for its sale on the basis of a calculation of their amount. But those who buy them can eat them when fresh.
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ بَشِيرِ بْنِ يَسَارٍ، عَنْ سَهْلِ بْنِ أَبِي حَثْمَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثَّمَرِ بِالتَّمْرِ وَرَخَّصَ فِي الْعَرَايَا أَنْ تُبَاعَ بِخَرْصِهَا يَأْكُلُهَا أَهْلُهَا رُطَبًا .
