Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: He heard the Prophet Muhammad (peace and blessings be upon him) say: "It is not permissible for any woman to observe a (voluntary) fast in the presence of her husband without his permission, nor can she allow any man into her house whom her husband dislikes. And whatever charity a woman gives, half of its reward will go to the man. The woman was created from a rib."
