The World Federation One Stop Fiqh

Ruling 801

If someone who has two sets of clothing knows that one of them is impure but he does not know which one it is, in the event that he has sufficient time, he must perform prayers with each of them. For example, if he wants to perform the ẓuhr and ʿaṣr prayers, he must perform one ẓuhr prayer and one ʿaṣr prayer with each. However, if time is short and neither of them can be preferred based on the strength of probability, then whichever one he performs his prayer with will be sufficient.
