حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، أَنَّ زَيْدًا أَبَا عَيَّاشٍ، سَأَلَ سَعْدًا عَنِ الْبَيْضَاءِ، بِالسُّلْتِ فَقَالَ أَيُّهُمَا أَفْضَلُ قَالَ الْبَيْضَاءُ . فَنَهَى عَنْ ذَلِكَ . وَقَالَ سَعْدٌ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يُسْأَلُ عَنِ اشْتِرَاءِ التَّمْرِ بِالرُّطَبِ فَقَالَ لِمَنْ حَوْلَهُ " أَيَنْقُصُ الرُّطَبُ إِذَا يَبِسَ " . قَالُوا نَعَمْ . فَنَهَى عَنْ ذَلِكَ .
Narrated 'Abdullah bin Yazid: "Zaid, Abu Ayyash asked Sa'd regarding white wheat in exchange for barley: which of them was better ? He said the white, then he forbade that. Sa'd said: 'I heard the Messenger of Allah (PBUH) being asked about selling dried dates for ripe dates and he said to those present: "Will the fresh dates shrink when they are dry ?" They said yes, so he forbade that.'" Translation Not Available
