—said, “One-fifth in a bequest is dearer to me, for Allah accepted one-fifth of the war-booty as a share. Whoever leaves behind wealth should realize that making a bequest augments his good deeds and compensates for what he neglected during his lifetime.
If someone bequeaths the full one-third that the law allows, the bequest is valid and must be executed. Should he bequeath more than one-third, anything beyond that limit is invalid unless the heirs approve it; they are free either to ratify or to refuse. If some heirs refuse while others consent, the consent is binding only on the portions of those who agreed, each according to his share. If all of them consent, the entire bequest is valid; if none of them consent, only the one-third takes effect.
All of this applies after the cost of his shroud, grave, and burial—at a reasonable, customary level—has been paid, and after his debts have likewise been settled, for neither inheritance nor bequest takes effect until the debts are discharged. Once the debts are cleared, the one-third specified in the bequest is taken out, if he designated it, and whatever remains is distributed among his heirs in the shares laid down in the Book of Allah, the Mighty and Majestic.
A bequest in favor of an heir is not permissible. If a person bequeaths anything, however small, to one of his heirs, that bequest is invalid unless the other heirs approve it after his death; with their approval it is valid, but without it the property returns to the estate, and the intended legatee receives only the statutory share due to him like the rest of the heirs. Should only some heirs approve, their approval is binding upon their own portions alone.
If a bequest is made jointly to an heir and to a non-heir, the heir may, if he wishes, share the bequest with the other beneficiaries and then consider what has reached them. Should all the heirs endorse the bequest in his favor, it is valid; if they refuse, the property reverts to the estate and is divided between him and them according to their respective shares.”
