Narrated By Ibn Abbas : That he was asked (regarding):

“Except to be kind to me for my Kinship with you.’ (42.23) Said bin Zubair (who was present then) said, “It means here (to show what is due for) the relatives of Muhammad.” On that Ibn Abbas said: you have hurried in giving the answer! There was no branch of the tribe of Quraish but the Prophet had relatives therein. The Prophet said, “I do not want anything from (you) except to be Kind to me for my Kinship with you.”
