Sunan Ibn Majah
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 .
It was narrated from Abu Hurairah that: The Prophet said to Hasan: "O Allah, I love him, so love him and love those who love him." He said: "And he hugged him to his chest."
