Is it permissible for a woman to donate all the land she owns to her only daughter, or to donate a portion of the land to her and bequeath one-third of the remainder for charitable work?

There is no harm in gifting an undivided share to your only daughter, whether it can be divided or not, according to the majority of scholars. A gift to an heir or a non-heir is valid if given while the grantor is in good health. There is no harm in bequeathing the remaining square meters to the poor and needy, while noting that a bequest is only valid for one-third of the estate, unless the heirs approve it if it exceeds one-third.
