Q: After work, I had washed my hands observing no obstructions (to water) on my skin. After a while, I noticed that there was, in fact, something on my hand that was preventing the access of water to an area of my hand’s skin. Assuming I had performed prayer with such an obstruction, what is my duty?
A: Assuming to grant it possible that the obstruction had appeared after making your wuḍū’, then all your previous prayers ought to be deemed valid. However, assuming you acknowledge the fact that it existed during your wuḍū’, the wuḍū’s and prayers performed after that are considered void.
