I was with Messenger of Allah ﷺ in one of the Markets of Medina. He left (the market) and so did I. Then he asked thrice, "Where is the small (child)?" Then he said, "Call Al-Hasan bin ʿAli." So Al-Hasan bin ʿAli got up and started walking with a necklace (of beads) around his neck. The Prophet ﷺ stretched his hand out like this, and Al-Hasan did the same. The Prophet ﷺ embraced him and said, "0 Allah! l love him, so please love him and love those who love him." Since Messenger of Allah ﷺ said that. nothing has been dearer to me than Al-Hasan.
