Is a son considered disobedient if he refuses to return a portion of the inheritance to his father, especially since the father is unjust and makes many demands? And are the prayers of unjust parents answered?

Scholars differ on the ruling concerning favoring some children over others in gifts. This may be permissible if the preference is for a reason and a need. If the son is dutiful to his father and stands by him in his affairs, it is permissible for the father to favor him in the gift, and this gift is valid.

A father may retract his gift to his son under certain conditions, including: the gift remaining in the son's possession, the son not incurring any obligation because of it, and no increase occurring to it.

However, a father taking money from some of his children for himself and his other children while he is wealthy is not permissible. The hadith "You and your wealth belong to your father" does not indicate the father's ownership of his son's money but rather permissibility under conditions. If the son prevents his father from taking his money in these situations, he is not considered disobedient. A parent's supplication against his child without a just cause is unlawful and will not be answered.
