Impermissibility of disposing of the inheritance without the heirs' permission

A: What the deceased left including the Mahr and jewelry is regarded as her estate from which her debts, if any, should be repaid and the payment of the bequest, if any, to the extent of one-third of the property should be made. The remaining amount of the estate goes to the inheritors. It is impermissible to dispose of this amount for any purpose other than that specified in the will unless the adult major heirs permit spending it on charitable activities on her behalf. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
