Which is more preferable: covering the 'awrah (part of the body that must be covered) with an impure garment, or leaving it uncovered?

Question : If a person prays and finds no garment other than an impure one, meaning, is the prayer with an impure garment forbidden, and is covering the 'awrah and praying with the 'awrah exposed also forbidden? Meaning, two forbidden things have come together for us, and we do not know which of these is more severe than the other?

Answer : Yes. Because if he covers his 'awrah, he has achieved the covering, and the exposure of the 'awrah is an apparent violation, while impurity is a hidden violation; the impurity of the garment may not be evident, so attending to it is more preferable. This is the first point. The second is that it is said that he covered his 'awrah with a garment from which he is unable to remove the impurity, so the obligation of removing it is lifted from him due to his inability to do so.
