One Who Forgets a Prayer and Does Not Know Which One It Was
Machine translationRead the Arabic original
Question:
Honorable Shaykh, this questioner says: A person forgot a prayer yesterday, and then the next day came, and he remembered that he had forgotten a prayer yesterday, but he does not remember which prayer it was, and he has neither doubt nor certainty. What is required of him in this situation?
Answer:
He has neither doubt nor certainty, and how is that? If he is certain that he has a prayer he did not perform, it is obligatory for him to make it up. If he does not know exactly which prayer it was, he should use his best judgment to determine the prayer, identify it through his effort, and make it up. However, if he has a doubt, I fear this is an obsessive thought (waswasah) for him. Doubt does not obligate him to do anything. Yes.
The presenter:
May Allah reward you
