If the ma'mum sees impurity on the imam's garment, should he inform him?

Question : If a believer sees impurity on the imam's garment, and the imam is unaware of it on his body, does the Shaykh say that it is obligatory for him to forbid this evil?

Answer : And what are you doing, people? He does not forbid an evil except with an evil. In this case, he will not forbid the evil except with an evil. What is the evil? It is cutting off my prayer. So in this case, if, as we said in the previous lesson, he prays alone and completes it for himself, and when he finishes he informs the imam, but I have something in mind, and the closest view I have established now is that he continues in his prayer, because the imam's prayer in this case is valid; this is the stronger position.
