Question : Now, in a fourth scenario. If he was ignorant of the ruling. If he was ignorant of the ruling. That is, he did not know that this is one of the impurities. He prayed, and then it became clear that it was an impurity. Is it obligatory for him to repeat the prayer, or not?

Answer : Yes, it is obligatory for him to repeat the prayer. That is, there is no difference between being ignorant of the impurity and being ignorant of the ruling regarding the impurity, or that it is an impurity. Is that clear? Good.
