Since the biggest reason for mistrust in parent-child relations is not-fulfilling promises made to the child, Ahl Al-Bayt (a.s) have emphasized the importance of keeping such promises. Imam Ali (a.s.) said, “Telling a lie is improper, whether being a joke or serious. It is also wrong when one of you promises his child and does not fulfill it, for lying leads to debauchery.” (1), and Imam Al-Kazim (a.s.) said, “When you promise children you must fulfill it for them, for they think it is you that gives them sustenance. Indeed, Allah does not get angry for anything the way He gets angry for the sake of women and children.” (2).
As implied in the sayings -especially the second- the child’s sense of trust is in the parents’ hands, thus they are parents who will be at fault if that trust is broken. The child should not be criticized or rebuked for not trusting their parents when they frequently promise them but do not fulfill that promise, or if the parent constantly tells them that they can come to them and talk about anything, but then flies into a rage when the child reveals something they do not want to hear.
