question #2 Sahih al-Bukhari 3497, Book 61, Hadith 7 : How does the Qur’anic verse 42:23 relate to the kinship of the Prophet Muhammad?

Ibn `Abbas recited the Qur’anic Verse:–‘Except to be kind to me for my kin-ship to you–” (42.23)
Sa`id bin Jubair said, “(The Verse implies) the kinship of Muhammad.” Ibn `Abbas said, “There was
not a single house (i.e. sub-tribe) of Quraish but had a kinship to the Prophet (ﷺ) and so the above Verse
was revealed in this connection, and its interpretation is: ‘O Quraish! You should keep good relation
between me (i.e. Muhammad) and you.”
