Ruling on the prayer of one who finds impurity in his garment

Question:
The brothers ask this question: If a person discovers that there is some impurity in his clothes and he has already prayed some of the obligatory prayers with them, are those prayers invalid?

Answer:
If he prayed while unaware of the impurity or forgetting about it, he owes nothing. If he finished his prayer and then found impurity in his garment, his prayer is valid, whether he was forgetting it after having known about it previously, or whether he was completely unaware of it. The correct view is that his prayer is valid and he does not have to repeat it. This is because it is established from the Prophet (peace and blessings be upon him) that "one day he prayed in his sandals, and Jibril alerted him that there was filth in them, so he took them off," and he did not restart his prayer but rather completed it, peace and blessings be upon him. This indicates that if a person prays in something containing impurity and does not know about it, his prayer is valid. However, once he knows, he should remove it. If he learns while in prayer, he should remove it, just as he would remove sandals, or a turban or head covering, or a cloak, while in prayer, and this does not harm him. As for if he cannot remove it because he has only one garment covering his 'awrah (nakedness) and impurity is found in it, he must break off the prayer in order to remove the impurity by washing or by changing the garment. Yes.
