أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثَّمَرِ بِالتَّمْرِ . وَقَالَ ابْنُ عُمَرَ حَدَّثَنِي زَيْدُ بْنُ ثَابِتٍ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَخَّصَ فِي الْعَرَايَا .
