It was narrated that ‘Abdul-Malik bin Maisarah said: I heard Tawoos say: Ibn 'Abbas (رضي الله عنه) was asked about this verse:

“Say (O Muhammad, unto mankind): I ask of you no fee therefore, save loving kindness among kinsfolk” (ash-Shoora 42:23). He said: Sa'eed bin Jubair said: It means loving kindness towards the family of Muhammad. Ibn 'Abbas (رضي الله عنه) said: You have been too hasty (in interpreting it)! There was no clan among Quraish but the Messenger of Allah (ﷺ) was connected to it by ties of blood. He said: (What it means is) except that you uphold the ties of kinship between you and me.
