عن ابي هريرة قال ما رأيت حسناً قط إلا فاضت عيناي دموعاً وذلك أن النبي ﷺ خرج يوماً فوجدني في المسجد فأخذ بيدي فانطلقت معه فما كلّمني حتى جئنا سوق بني قينقاع فطاف فيه ونظر ثم إنصرف وأنا معه حتى جئنا المسجد فجلس فاحتبى ثم قال أين لكاع ادعُ لي لكاع فجاء حسن يشتدّ فوقع في حجره ثم أدخل يده في لحيته ثم جعل النبي ﷺ يفتح فاه فيُدخل فاه في فيه ثم قال اللهم إني أحبه فأحبِبه وأحبّ من يحبه
الأدب المفرد للبخاري باب الاحتباء
From Ahu Huraira who said: There was never a time I saw Hasan but that my eyes overflowed with tears. This was because one day the Prophet (SAW) went out and found me in the mosque, and He took me by the hand, and I went out with Him. And He did not talk to me until we got to the market of the Banu Qaynaqa’. He went around in it, had a look, and then left, and I was with Him, until we came back to the mosque. He sat down, crouched down, and drew his garment around Himself, and then said: Where is a little rascal girl [laka’]? Call a little rascal girl to me. And Hasan came in running and jumped into His lap, and put his hand into His beard. Then the Prophet (SAW) took and opened up his mouth, and put His mouth into his mouth, then said: Oh Allah, truly I love him, so love him also and love the one who loves him.
