What is the ruling on money acquired by a father from his work in an insurance company, and is it permissible for the children and mother to benefit from it, and is it permissible to accept gifts from him (apartments and money)?

Commercial insurance contracts are forbidden by Sharia due to their inclusion of gharar (excessive uncertainty) and maysir (gambling). Your father should leave his work at the insurance company, especially after reaching seventy. The money earned from this work is permissible for him as long as he earned it before knowing of its prohibition, and it becomes forbidden after he learns of it. As for the wife and children, there is no sin upon them in benefiting from the money that the father spends on them, and the sin is upon him alone, based on the Prophet's acceptance of gifts from Jews and his eating from their food. The money earned from this work is permissible for the children, but if the money was taken unjustly, it must be returned to its rightful owners or given away as charity.
