Question:
Honorable Shaykh! A man prayed the 'Asr prayer, and after the prayer he remembered that he had not wiped his head, and this is certain, not a doubt. What should he do?
Answer:
If it is merely a doubt after the prayer, he does not repeat it. If it is merely a doubt after the prayer, even after the wudu', if he finished the wudu' and doubted whether he wiped his head or not, he says: I do not doubt after the act of worship. But if he is certain, he takes water and wipes his head, then he repeats the wudu' and repeats the prayer. Yes.
