Is it permissible to supplicate against one's father and wish for his death due to his cruelty and injustice towards the mother and children, and his prevention of the children from disposing of their own money?

The father's harshness and cruelty towards his family are a trial, and this must be met with patience, kindness, and good treatment towards him. Being kind to him includes supplicating for his guidance and for his situation to improve. It is not permissible to supplicate against him or wish for his death.

A father does not have the right to prevent his children from communicating with relatives, especially those of kinship, because cutting off ties of kinship is forbidden.

The money you earn is exclusively yours, and your father is not entitled to take from it except under certain conditions.

It is the mother's right that the father spends on her and provides her with the necessities of life. If he prevents her from her right, she is allowed to take from his money an amount sufficient for her maintenance.

Effort must be made to improve the father's situation by supplicating for him and seeking help from friends and relatives whose advice he might accept.
