الترمذي:٣٧٧٧ – حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي خَالِدٍ عَنْ أَبِي جُحَيْفَةَ قَالَ

رَأَيْتُ رَسُولَ اللَّهِ ﷺ وَكَانَ الْحَسَنُ بْنُ عَلِيٍّ يُشْبِهُهُ  

هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَفِي الْبَابِ عَنْ أَبِي بَكْرٍ الصِّدِّيقِ وَابْنِ عَبَّاسٍ وَابْنِ الزُّبَيْرِ
