Is it permissible for a person to grant a house to his brother with a deed of ownership, on condition that the brother benefits from it only during his lifetime, and then the house returns to the grantor after the beneficiary's death? And is this considered one of the permissible forms of Umra if the grantor agrees to this condition?

According to scholars, a lifetime gift (ʿumra) entails transferring both ownership and usufruct, as the Prophet, peace and blessings be upon him, said: "Whoever grants a lifetime gift, it belongs to the one to whom it was granted, alive and dead, and to his offspring." However, if a person fully gifts a house to his brother, and the donee takes possession of it, the house becomes the property of the donee brother. If he wishes to return the house to the donor after his death, it is considered a bequest and not a lifetime gift.
