The ruling on one who prays while there is impurity in his garment

Question:
If a person remembers that there is impurity in his garment after he has entered the prayer, but he does not know the location of that impurity, what should he do?

Answer:
If he knows that there is impurity on him, which is what is upon him, after he has entered the prayer, then if he has something that covers him, he removes it immediately and prays in what he has on, such as trousers, a shirt, or a garment, or if there is another garment underneath. If he has no garment, he breaks the prayer and goes to add to this garment or wear something else, or he washes it as Allah has commanded, and he washes it, and he prays in it. If he did not remember until after the prayer, and note that this is after the prayer, his prayer is valid. If he prayed in a garment with impurity but did not notice until after the prayer, after he had said the taslim, his prayer is valid. This is because it was established from him (peace and blessings be upon him) that he prayed one day while he had on his garments, and then Jibril came to him and mentioned that there was impurity in them. He removed them and then completed the prayer, and he did not repeat the first part of the prayer, (peace and blessings be upon him). This indicates that if one has impurity in his garment and does not know until after the prayer, he does not repeat his prayer; it is valid according to the stronger opinion. As for if he learns of it during the prayer, if he is able to remove it, he looks at his garment, his shoes, his feet, or if there is a garment underneath, he removes it and prays in the clean garment underneath. As for if he has nothing on him but the garment with impurity, he breaks the prayer and goes until he wears a pure garment, or he carries this garment and then prays, even if he is alone if the congregation has passed. If one is required to.
This indicates that in any case, he prays with the people or as an imam. But when he prayed, he realized that he was in a state of purity, indicating purity. And if he realized that he was in a state of purity, or in a state of major ritual impurity, this one repeats the prayer. He performs wudu' or ghusl and repeats the prayer. Who knows this? The one who gathered the scholars. Note that if one prays in a state of purity while in a state of purity, he repeats the prayer, unlike the one who prayed in a garment with impurity. This is more similar to one who prayed in a state of impurity and did not know until after the salam. This one does not repeat, because the presence of impurity in the garment is easier than the absence of purity.
