Is it permissible for the heirs to extract an additional amount from the bequeathed one-third and distribute it among the other grandchildren, out of consideration for their feelings?

The testator's condition in the will must be adhered to, and the heirs are not permitted to alter it. If the remaining grandchildren do not meet the condition of the will, then nothing should be disbursed to them. If the testator bequeathed to the poor, and some of his grandchildren or relatives who are not heirs are poor, then they have precedence over other strangers. It is desirable to include as many poor people as possible and to give them according to their needs, starting with the testator's relatives who are not heirs, then his mahram (definition) relatives through fosterage, then his neighbors.
