What is the ruling on doubting the uncovering of the 'awrah during prayer?

Concealing the 'awrah (private parts) is one of the conditions for the validity of prayer. Jurists divide the 'awrah into severe and light. If someone prays having covered their 'awrah, then doubts whether it became uncovered during the prayer, their prayer is valid, and the doubt does not harm it. The original presumption is the validity of the prayer, and it is not invalidated merely by doubt.
