When One Doubts If He Has Performed the Two Sajdahs or Not
Issue No. 1082 - If a person is reciting tashahhud or enters the following rak‘at and doubts whether he has performed the two sajdahs or not, and at the same time falls again into a type of doubt [about the rak‘ats] which would be valid only if it occurred after completing two sajdahs (e.g. doubt between two and three rak‘ats), in this case, one should assume that he has performed two sajdahs and should act according to the rules of doubt, making his prayer would be correct. However, if the doubt occurs when the time of sajdah has not passed yet, the prayer will be void.
