If he could take away the clothes, but had no other clothes, he would complete the prayer in that same clothes. The following najasah are excused in the prayer: (a) The blood which comes out of wound or tumor provided it is difficult to clean it or, at least change the bandage once a day. But if that blood reaches another part of the body which is far from that tumor or wound it is not excused; it must be cleansed.
provided they are not made from najasah like dead body, dog, etc. It is not allowed to keep these things in prayer even without wearing them. (d) The clothes of the woman, who rears up an infant boy, provided that: The clothes have become najis with his urine; And she has no other clothes to change into. In this case, she is allowed to clean the clothes once a day and then ignore the najasah of his urine afterwards.
