Abu Hurairah reported,

The Messenger of Allah ﷺ went out to the market of Banu Qaynuqa, leaning on my hand. He walked through it, then returned and sat in the mosque with his garment wrapped around his knees. He said, "Where is the little one? Call the little one to me."Hasan came running and leapt into his lap. The Prophet ﷺ put his mouth on the boy's mouth, then said, "O Allah, I love him, so love him, and love whoever loves him," repeating it three times.Abu Hurairah said, "I never saw Hasan after that without my eyes overflowing," or "without my eyes tearing up," or "without weeping." The doubt is from al-Khayyat.

حدثنا حماد الخياط حدثنا هشام بن سعد عن نعيم بن عبد الله المجمر

عن أبي هريرة قال

خرج رسول الله ﷺ إلى سوق بني قينقاع متكئا على يدي فطاف فيها ثم رجع فاحتبى في المسجد وقال أين لكاع ادعوا لي لكاعا فجاء الحسن عليه السلام فاشتد حتى وثب في حبوته فأدخل فمه في فمه ثم قال اللهم إني أحبه فأحبه وأحب من يحبه ثلاثا قال أبو هريرة ما رأيت الحسن إلا فاضت عيني أو دمعت عيني أو بكت شك الخياط
