According to Islam can a man give orders to his spouse? For example can he order his wife to pray ? Or in any other issues?
Nobody can be forced to worship because worship depends on self intention. A man should inspire and advice his wife not to discontinue worships. This is one of the most appreciated good deeds in Islam.
