What is the ruling of Islamic law regarding a husband writing all of his properties in his father's name instead of keeping them in his own name, fearing the loss of his wife's and children's right to inheritance?

A husband's spending on his father and brothers is an act of piety. As for registering his properties in his father's name, this can be interpreted in several ways:

1. A gift (Hibah): This is permissible as long as the owner is in good health. However, it is recommended that he retain something for his children and wife, based on the Prophet's (peace be upon him) saying: "It is better for you to leave your heirs wealthy than to leave them poor, begging from people."

2. A will (Wasiyyah): If this takes effect after his death, it is a will made to an heir, which is forbidden by Islamic law.

3. For another purpose: Such as facilitating legal procedures. This is permissible in principle if it does not involve actual ownership transfer. However, he should have witnesses attest that these properties belong to him and not to his father, to avoid the loss of heirs' rights in the future.

The wife is advised to counsel him gently and wisely, explaining the potential harms resulting from such an action.
