Is it permissible to bequeath to a minor when his mother is among the heirs and possesses abundant wealth?

There is no objection to a will made by the deceased for minors if the conditions for a will are met, even if the mother of the legatee is an heir or wealthy. A will is legislated for relatives regardless of their wealth or poverty, though it is preferable to prioritize the poor. The will for close relatives was once obligatory, but its obligation was later abrogated. Evidence for the permissibility of a will for a relative who is also an heir is what was authentically reported about Az-Zubair ibn Al-Awwam, may Allah be pleased with him, that he bequeathed one-third of his wealth to the sons of his son Abdullah ibn Az-Zubair, which indicates the permissibility of a will for grandchildren even if their fathers are alive.
