Doubts in Other Obligatory Prayers
Issue No.1098- There is no difference between the rules of doubt, inadvertence, and presumption regardless of its occurring in the daily obligatory prayers or other obligatory prayers. For example, if one doubts in Signs (āyāt) Prayer whether he has performed one rak‘at or two, his prayer will be void since it is a doubt which has occurred in a two rak‘ats prayer; similar to other rules of doubt, inadvertence and presumption.
