Building a Masjid and dedicating it as Waqf

Q 1: A man passed away and left behind his wife and 54,000 Riyals, which is the value of the compensation for a house he inherited from his mother. The only heir of this man is his wife, for he was barren. His wife wants to spend the mentioned sum in building a Masjid (mosque) as Waqf (endowment) for the sake of Allah on behalf of her husband, his mother and herself. Is this action permissible?

A: If the reality is as you have mentioned, she may do so because it is an act of charity. (Part No. 16; Page No. 31) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
