Is it permissible to designate a plot of land as an endowment (waqf) for the deceased woman before the distribution of the inheritance, with or without the agreement of all heirs? And is her will to distribute the inheritance equally between males and females, excluding the husband, to be carried out? And should two plots of land be given as a gift to the children of her deceased son?

If a woman dies leaving a husband, two sons, and two daughters, and no other heirs, then her husband receives one-fourth as a prescribed share due to the existence of inheriting lineal descendants. The sons and daughters receive the remainder by ta'sib (agnatic inheritance), with the male receiving a share equal to that of two females. The inheritance—after the execution of any obligatory bequests—is divided into eight shares: the husband receives two shares, each son receives two shares, and each daughter receives one share.

As for the deceased's will that the distribution to the male children be equal to that of the females, and that the husband not be given anything, this is a void will and shall not be executed, because it contradicts the ruling of Allah Almighty concerning inheritance.

Her bequest of some land to her grandchildren from her deceased son is considered a valid bequest to a non-heir, and it shall be executed within the limits of one-third of the estate only. Anything exceeding one-third requires the consent of the adult heirs.

If the heirs agree to designate some of the land as waqf (endowment), there is no objection to that, provided that all adult heirs consent.
