What is the legitimate legal opinion regarding depriving the female descendants of the endower of their share in his endowment during their lifetime, while giving it to individuals who are not related to him by kinship, and what are the legitimate legal proofs for this from the Quran and Sunnah?

The question asked by the inquirer is unclear. However, if she means the inclusion of daughters' children in an endowment (waqf) designated for offspring (dhürriyah), then this is a matter of dispute among jurists. The preponderant view is their inclusion due to the strength of its evidence. We have previously mentioned the basis for those who argue against their inclusion and the weakness of their opinion. Such matters are resolved through judicial rulings to settle the dispute.
