question #3 Sahih al-Bukhari 5884, Book 77, Hadith 101 : What can be learned about the relationship between the Prophet and his grandchildren from this narration?

I was with Allah’s Messenger (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 `Ali.” So Al-Hasan bin
`Ali 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 Allah’s Messenger (ﷺ) said that. nothing
has been dearer to me than Al-Hasan.
