حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ، عَنْ نَافِعِ بْنِ جُبَيْرٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ لِلْحَسَنِ " اللَّهُمَّ إِنِّي أُحِبُّهُ فَأَحِبَّهُ وَأَحِبَّ مَنْ يُحِبُّهُ " . قَالَ وَضَمَّهُ إِلَى صَدْرِهِ .
