The Criterion for Doubt in Prayer and Whispers

Question:
Honorable Shaykh, may Allah preserve you, what is the criterion for doubt in prayer so that one can distinguish it from the whispers (waswasah) that occur?

Answer:
We have defined it for you. We said that doubt is the hesitation between two matters where neither is more probable than the other. This is doubt. However, if one is more probable than the other, one acts according to the stronger probability, which is called the preponderance of opinion (ghalbat al-zann). It is called the preponderance of opinion. If one of the two possibilities is stronger than the other, one acts according to the stronger one, which is called the preponderance of opinion. As for the other side, the weaker one, this is called a delusion (wahm). They call it a delusion: hesitation between two matters, one of which is stronger and the other weaker. The stronger one is called opinion (zann), and the weaker one is called a delusion (wahm) or a whisper (waswasah), and a person should leave it alone. Yes.
