Is it permissible to disinherit disobedient children who sow discord and seek to break up the family, in order to prevent discord with their siblings?

If the father wishes to deprive his children of gifts or inheritance, he can refer to the mentioned fatwas. The father has done well in raising them upon the creed and morals of Islam, and he should not despair of their guidance. He should supplicate for them frequently, and he can also enlist someone who influences them to advise them. If the mother and the two daughters remove their hijabs, they have committed a grave transgression, and they must be reminded of the danger of displaying themselves. If the son marries off his sister without the father's permission and without a valid reason, he has acted wrongly, and there is a difference of opinion regarding the ruling on this marriage.
