حَدَّثَنَا أَبُو سَعِيدٍ الأَشَجُّ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ ضَحَّى رَسُولُ اللَّهِ صلى الله عليه وسلم بِكَبْشٍ أَقْرَنَ فَحِيلٍ يَأْكُلُ فِي سَوَادٍ وَيَمْشِي فِي سَوَادٍ وَيَنْظُرُ فِي سَوَادٍ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ حَفْصِ بْنِ غِيَاثٍ .
