Is the father entitled to take possession of a gift on behalf of his minor son, and is taking possession of it contingent upon the permission of the heirs after the father's death, given that the father intended to equalize his children through this gift?

Since you were young when your father passed away, his possession of the property and his gift of it to you are valid and sound, for a father takes possession of a gift on behalf of his young child. Scholars have unanimously agreed on the validity of a man's gift to his young child if he takes possession of it for him himself. This is further confirmed by your father registering the property's utilities in your name during his lifetime. Furthermore, justice between you and your siblings concerning your father's gifts is achieved through this gift. Some scholars believe that a gift in which justice has not been achieved is invalid and must be returned to the estate after the death of the giver.
