Since fasting, in relation to the servants, introduces corruption since it is susceptible to that and accepts righteousness as well, then the offer is to the Lord of the worlds and not in the name of anyone else, and the Lord is the reformer, so He will correct whatever corruption has entered into this fast if corruption has entered into it from where he does not realize it, and this ruling is related to the sign. Particularly, it is the indication of God Almighty, and for this reason he said, “On the Lord of the Worlds, of the sign, and the corruption of the sign is only because of the suspicion raised about it in the rational view, and there is no greater suspicion than attributing fasting to God over all other deeds and describing the servant with it.” Then the demonstration occurs, which is the manifestation and revelation that the fasting person has what God has of him. Fasting and what the servant has of it, so the doubt accepted by the mind is removed by divine revelation.
