Abu Huraira reported Allah's Messenger as saying to Hasan: O Allah, behold, I love him. Thou too love him and love one who loves him.
حَدَّثَنِي أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ أَبِي يَزِيدَ، عَنْ نَافِعِ بْنِ جُبَيْرٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ لِحَسَنٍ " اللَّهُمَّ إِنِّي أُحِبُّهُ فَأَحِبَّهُ وَأَحْبِبْ مَنْ يُحِبُّهُ " .

Abu Huraira reported: I went along with Allah's Messenger at a time during the day but he did not talk to me and I did not talk to him until he reached the market of Bani Qainuqa`. He came back to the tent of Fatima and said: Is the little chap (meaning Hasan) there? We were under the impression that his mother had detained him in order to bathe him and dress him and garland him with a sweet garland. Not much time had passed that he (Hasan) came running until both of them embraced each other, thereupon Allah's Messenger said: O Allah, I love him; love him Thou and love one who loves him (Hasan).
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ، عَنْ نَافِعِ بْنِ جُبَيْرِ، بْنِ مُطْعِمٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ خَرَجْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي طَائِفَةٍ مِنَ النَّهَارِ لاَ يُكَلِّمُنِي وَلاَ أُكَلِّمُهُ حَتَّى جَاءَ سُوقَ بَنِي قَيْنُقَاعَ ثُمَّ انْصَرَفَ حَتَّى أَتَى خِبَاءَ فَاطِمَةَ فَقَالَ " أَثَمَّ لُكَعُ أَثَمَّ لُكَعُ " . يَعْنِي حَسَنًا فَظَنَنَّا أَنَّهُ إِنَّمَا تَحْبِسُهُ أُمُّهُ لأَنْ تُغَسِّلَهُ وَتُلْبِسَهُ سِخَابًا فَلَمْ يَلْبَثْ أَنْ جَاءَ يَسْعَى حَتَّى اعْتَنَقَ كُلُّ وَاحِدٍ مِنْهُمَا صَاحِبَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اللَّهُمَّ إِنِّي أُحِبُّهُ فَأَحِبَّهُ وَأَحْبِبْ مَنْ يُحِبُّهُ " .
