أبو داود:١٧٣٥حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ أَخْبَرَنِي ابْنُ أَبِي ذِئْبٍ عَنْ عُبَيْدِ بْنِ عُمَيْرٍ قَالَ أَحْمَدُ بْنُ صَالِحٍ كَلاَمًا مَعْنَاهُ أَنَّهُ مَوْلَى ابْنِ عَبَّاسٍ عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ

أَنَّ النَّاسَ فِي أَوَّلِ مَا كَانَ الْحَجُّ كَانُوا يَبِيعُونَ فَذَكَرَ مَعْنَاهُ إِلَى قَوْلِهِ مَوَاسِمِ الْحَجِّ
