Is it permissible for a woman who has willed her property to the sons of her paternal uncle's son – who are not among her heirs – to do so, while she has other heirs? Is it permissible for the donees to benefit from what was bestowed upon them? Do the heirs have the right to claim what was bestowed? And do they have a share in these properties?

If a woman donates her money while she is healthy and of sound mind, and the donation is executed during her lifetime and the donees take possession of it, then it is a valid gift Islamically, and the heirs are not permitted to claim any part of it. However, if the donation is contingent upon her death, then it falls under the ruling of a will, and thus, anything exceeding one-third of it is not executed, and it is not valid to be given to an heir.
