if the house was his entire property, and he endowed it all, then according to the position we have chosen, the ruling regarding it is the same as if it were within the third, for an heir regarding the entire estate is like a stranger regarding what exceeds the third. As for the report narrated by the group, the endowment is binding upon the third without the heirs' choice, and regarding what exceeds it, both [the son and the daughter] have the right to void the endowment. The son has the right to void the equalization. If he chooses to void the equalization without voiding the endowment, two positions have been derived from it: one is that the endowment becomes void in one-ninth, and it returns to him as property, so he ends up with one-half as an endowment and one-ninth as property, while the daughter has one-sixth and two-ninths as an endowment; this is because the son only possesses the right to void the endowment in what belongs to him, not what belongs to someone else. The second position is that he has the right to void the endowment in one-sixth, and he ends up with one-half as an endowment and one-ninth as property, while the daughter has one-third as an endowment and one-half of a ninth as property, so that the daughter does not exceed the son in the endowment. The issue in this position is resolved into eighteen: the son has nine as an endowment and two shares as property, while the daughter has six shares as an endowment and one share as property. Abu al-Khattab said: He has the right to void the endowment in the entire one-fourth, and he ends up with one-half as an endowment and one-sixth as property, and the daughter has one-fourth as an endowment and one-half of one-sixth as property, as if the house were within the third, and it is resolved into twelve.

925 - Issue; he said: (And when an endowment becomes dilapidated and does not yield anything, it is sold, and with its price, that which will benefit the people of the endowment is purchased, and it is made an endowment like the first. Likewise, the tethered horse (al-faras al-habis), when it is no longer fit for military expeditions, is sold, and with its price, that which is fit for Jihad is purchased.)

The entirety of this is that when an endowment becomes dilapidated and its benefits cease, such as a house that has collapsed, or land that has become ruined and returned to being wasteland where its restoration is impossible, or a mosque from which the villagers have moved and it has become in a location where one cannot pray, or it has become too narrow for its people and it is impossible to expand it in its current location,
