Maintaining the ties of kinship entails treating relatives kindly by visiting them and helping them in any way.
As for being undutiful to parents, it means disobeying them, harming them, treating them unkindly and similar acts that are considered severing ties with them. (Part No. 25; Page No. 295) A parent's right over their children is obedience in anything other than whatever involves disobedience to Allah and kind treatment whether by words or actions. On the other hand, a child's right over their parent is to choose them a good name, provide and care for them, offer them moral support and guidance to the best manners and teach them life and religious affairs.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
