أبو داود:٣٤٩٧ – حَدَّثَنَا مُسَدَّدٌ وَسُلَيْمَانُ بْنُ حَرْبٍ قَالاَ حَدَّثَنَا حَمَّادٌ ح وَحَدَّثَنَا مُسَدَّدٌ حَدَّثَنَا أَبُو عَوَانَةَ وَهَذَا لَفْظُ مُسَدَّدٍ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ طَاوُسٍ عَنِ ابْنِ عَبَّاسٍ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا اشْتَرَى أَحَدُكُمْ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَقْبِضَهُ قَالَ سُلَيْمَانُ بْنُ حَرْبٍ حَتَّى يَسْتَوْفِيَهُ زَادَ مُسَدَّدٌ قَالَ وَقَالَ ابْنُ عَبَّاسٍ وَأَحْسِبُ أَنَّ كُلَّ شَىْءٍ مِثْلُ الطَّعَامِ
