Narrated Tawus: Ibn 'Abbas was asked about this Ayah: Say: "No reward do I ask of you for this except to be kind for my kinship with you (42:23)." So Sa'eed bin Jubair said: “To be kind to the family of Muhammad.' Ibn 'Abbas replied: “You know that there was no family of the Quraish except that the Messenger of Allah (ﷺ) had some relatives among them.' He said: “Except that you should uphold ties of kinship that exist between me and you”””
