What is the ruling on parents who do not want to see their children, and what is the ruling on harshness toward children?

Question : Honorable Shaykh, this sister who is asking with us says: Regarding the parents, if they have a desire or no desire for this child to maintain contact with them—they have a child, but they have no desire to communicate with them or maintain contact with them—what is the ruling on that? And what is also the ruling on the harshness of the parents toward the child? May Allah reward you.

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, the Seal of the Prophets and the Imam of the Pious, and upon his family and his Companions, and those who follow them with excellence until the Day of Judgment. It is obligatory for the children, both male and female, to be dutiful to their parents. Indeed, undutifulness to parents is among the major sins. Rather, it is among the greatest of the major sins. It is obligatory for the parents, the mother and the father, to maintain the ties of kinship with their children. Because maintaining family ties is among the best of deeds, and severing family ties is among the causes of severance in this world and the Hereafter. It is not permissible for the parents to reject the dutifulness of their children, whether male or female. Rather, it is obligatory for them to assist in the dutifulness of their children. It is not permissible for the children, whether male or female, to be undutiful to their parents. Rather, they must be dutiful and excellent in their conduct. If severance occurs from the fathers and mothers, the sin is upon the one who severs. Let this child strive to maintain contact with his parents, whether they are pleased with that or they dislike it.
Rather, he should go to their house and knock on the door. Until if they say, "Go away, stay away, do not harm us," he has fulfilled the obligation upon him, so let him leave. Then let him come again after two or three days and do as he did the first time. And in that case, he has fulfilled his dutifulness to his parents, while they have committed the severance of family ties. I ask Allah for guidance for everyone.
