Faith is the origin and action is undoubtedly a branch of this origin. Therefore, unless a believer is completely disobedient without mixing it with obedience, then the mixture is the disobedient believer. If the believer disobeys in a matter, then he believes that it is a sin, and faith is obligatory, for he has fulfilled an obligation. The believer will be rewarded in the very essence of his disobedience, and faith is stronger.
