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 ‏.‏
