Unauthorized use of property by father and son

Your problems and their solutions

Question: Can a father take his son’s property or things without his permission? Similarly, what is the ruling on a son taking his father’s property without his consent and doing business with him?

Answer: It is not permissible for a father to take his son’s property without his permission. If the father is in need, then his maintenance is obligatory on the son and if the son does not fulfill this responsibility, then the father can take from the son’s property as much as he needs without permission. If the son has taken the father’s property without his consent, then he has done something illegal and it is obligatory on him to return the same amount to the father. The business of this property belongs to the son, but the profit is not halal for the son, but his charity is obligatory.
