Q: I am a barren lady whose husband married a second wife and got children. All praise be to Allah Alone, I have gold and money that I would like to endow. I do not like to give any thing to my siblings or husband bearing in mind that I support myself for my husband does not provide for me and I pay the rent of the house.
Is it then permissible for me to endow everything that I have and deprive my husband and family of it?
It is permissible that you make an effective Waqf (endowment) while you are alive provided that it is spent on charitable ways of disposition and that your intention is not to deprive your inheritors of anything. However, if that Waqf is to be effective after you die, it is only permissible for non-inheritors within one third or less. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
