I went along with Messenger of Allah ﷺ 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 Qainuqaʿ. 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 Messenger of Allah ﷺ said: O Allah, I love him; love him Thou and love one who loves him (Hasan).  

مسلم:٢٤٢١bحَدَّثَنَا 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 ﷺ 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 ﷺ اللَّهُمَّ إِنِّي أُحِبُّهُ فَأَحِبَّهُ وَأَحْبِبْ مَنْ يُحِبُّهُ

Once the Prophet ﷺ went out during the day. Neither did he talk to me nor I to him till he reached the market of Bani Qainuqa and then he sat in the compound of Fatima's house and asked about the small boy (his grandson Al-Hasan) but Fatima kept the boy in for a while. I thought she was either changing his clothes or giving the boy a bath. After a while the boy came out running and the Prophet ﷺ embraced and kissed him and then said, 'O Allah! Love him, and love whoever loves him.'  

البخاري:٢١٢٢حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ حَدَّثَنَا سُفْيَانُ عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ عَنْ نَافِعِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ

عَنْ أَبِي هُرَيْرَةَ الدَّوْسِيِّ ؓ قَالَ خَرَجَ النَّبِيُّ ﷺ فِي طَائِفَةِ النَّهَارِ لاَ يُكَلِّمُنِي وَلاَ أُكَلِّمُهُ حَتَّى أَتَى سُوقَ بَنِي قَيْنُقَاعَ فَجَلَسَ بِفِنَاءِ بَيْتِ فَاطِمَةَ فَقَالَ أَثَمَّ لُكَعُ أَثَمَّ لُكَعُ فَحَبَسَتْهُ شَيْئًا فَظَنَنْتُ أَنَّهَا تُلْبِسُهُ سِخَابًا أَوْ تُغَسِّلُهُ فَجَاءَ يَشْتَدُّ حَتَّى عَانَقَهُ وَقَبَّلَهُ وَقَالَ اللَّهُمَّ أَحْبِبْهُ وَأَحِبَّ مَنْ يُحِبُّهُ قَالَ سُفْيَانُ قَالَ عُبَيْدُ اللَّهِ أَخْبَرَنِي أَنَّهُ رَأَى نَافِعَ بْنَ جُبَيْرٍ أَوْتَرَ بِرَكْعَةٍ
