What should the three daughters do if the father creates problems to force them to relinquish the inheritance he wrote for them, knowing that he will deprive them of their inheritance, and that this property is a refuge for one of them, especially since one of them is mentally ill and another is poor?

Injustice is forbidden, and mistreatment of children is a great corruption. Depriving one of the heirs of their right is a forbidden oppression, and causing harm in a will is among the grave sins. Nevertheless, a father's injustice does not justify disobedience towards him. Rather, honoring him is obligatory, and associating with him in kindness. What is termed a sale, with the final ownership deferred until death, is an invalid will, because there is no will for an heir, and the father can reclaim the properties. Spend on yourselves with kindness, and strive to advise the father and supplicate for his guidance, seeking assistance from those who hold influence with him.
