Should the will of the deceased mother to allocate her gold to the daughters only be carried out if it does not exceed one-third of the inheritance, or should the gold be distributed according to Islamic law among all heirs, including the deceased nephew, and is it permissible to compensate the deceased nephew for his share of the gold in cash?

A mother's bequest of gold to her daughters is a bequest to an heir, which is religiously prohibited and does not take effect unless the rest of the heirs agree to it. They must be informed of this. Whoever agrees to waive their share may do so, and whoever wishes to claim their share may do so. As for the son of the son, he does not inherit when the son is present, because he is blocked by him, and he gets nothing unless his grandmother bequeaths something to him, provided it does not exceed one-third, and the law of compulsory bequest is not to be considered.
