Is it permissible to designate the name of one of the heirs to exclusively receive the full amount of assistance from the Takaful fund after death, knowing that it is not considered part of the inheritance?

The money disbursed from Takaful insurance upon death is considered part of the deceased's inheritance (tarakah), because it entered his possession after his death due to an action he took during his lifetime. It should be divided among his heirs according to Islamic law. If the purpose of registering the name of one of the heirs is to facilitate the receipt of money from the bank, then the money must be included in the estate and divided among all heirs, and precautions should be taken to safeguard the rights of the other heirs. However, registering the name of an heir for him to exclusively own the money is not permissible without the permission of the remaining heirs.
