The second reason is that the Imam, who is the Sharia to be followed, has a say and a ruling, and whatever he has reached, then if he sets out to achieve the station and completes it according to what he knows, he sees a deficiency in its result, so he seeks knowledge of the reason, and finds himself leaving out what he should have used, but he had no knowledge. Thus, he found a prophetic hadith or a verse from the Book of God Almighty and missed acting on that, so he worked on that and the results of his standing were valid for him. This is in the same position as what he missed from the imam’s prayer .
