What is the ruling on a son owning an apartment, a car, and a sum of money that his mother gifted to him during her lifetime? Is it permissible for the money to remain in an Islamic bank to benefit from its profits until the inheritance is distributed? What is the ruling on a mother registering her apartments, which vary in value, in the names of her sons during her lifetime to avoid disputes after her death?

The mother must be equitable among her children in gifting, by giving the remaining children the same amount that one of them was given, or by returning what was taken. If she does not achieve equity, and the rest of the children are content with the preference given to one of them, then there is no harm in accepting the gift and benefiting from it. Otherwise, it must be returned.

As for writing over apartments, if the intention is to transfer ownership during lifetime, it is a gift that requires equity. If the intention is to transfer ownership after death, it is a will to an heir, which is not permissible unless approved by the heirs.
