Volume 4, Book 56, Number 701:
Narrated Tawus:
Ibn ‘Abbas recited the Quranic Verse:–‘Except to be kind to me for my kin-ship to you–” (42.23)
Said 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 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.”
