What is the ruling of Sharia on a wealthy father seizing the money of his poor and sick son, including debts owed to the son by the father, money sent to the son by his uncle for studies that the father seizes, and property the father stole and usurped from him, and is it permissible for the father to evict his son from a house the son built with his own money, and what is the ruling on a father squandering his son's money and accusing him of false charges?

The majority of jurists hold that a father is not permitted to take his son's money except out of necessity or with the son's consent. If he takes from his son's money without these conditions, he has committed a wrong and an injustice. The son is permitted to demand his right from his father, but he should deal with him gently and without insistence. He can seek the help of relatives or friends. The son must honor his father and treat him kindly, even if the father wrongs him, for mistreating the father is a form of disobedience to parents.
