Is the money saved by the mother from her children's funds to be divided among them equally after her death, or in proportion to what each of them paid?

If the money is given to the mother as a gift and a gesture of kinship, it is her property and is to be divided among her heirs after her death. However, if the money is a loan, she owns it during her lifetime, and if she does not repay it, it must be repaid from her estate before division, in accordance with the verse: (after any bequest which he may have made or any debt).
