Do the heirs have a legitimate right to the house they live in, or does it remain for the wife and her children?

What the deceased leaves behind after their preparation, settlement of debts, and execution of their will is considered an inheritance, and this includes the house they lived in and any other properties. This is based on the Prophet's (peace be upon him) saying: "Whoever leaves behind wealth, it is for his heirs." If the deceased has a male child, only his wife and parents inherit with him, while siblings and others are excluded. All children from different wives share in the inheritance of the house, unless the father had gifted it to his wife during his lifetime.
