حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ كَانُوا يَبْتَاعُونَ الطَّعَامَ فِي أَعْلَى السُّوقِ فَيَبِيعُونَهُ فِي مَكَانِهِمْ، فَنَهَاهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَبِيعُوهُ فِي مَكَانِهِ حَتَّى يَنْقُلُوهُ.
