If a Kathīr al-Shak Doubts whether or not He Has Performed a Foundational Element
Issue No. 1067 - If a Kathīr al-shak person doubts whether or not he has performed a foundational element (e.g. rukū‘), and ignores his doubt, but remembers later that he had actually not performed it he should perform it, if he has not entered into the next foundational element (rukn). And if he has entered the next foundational element, his prayer is void. But if he doubts about an act, which is not a foundational element and remembers later that he had not performed it, and has not yet commenced the next foundational element, he should perform it, and if he has entered the next foundational element, he should not go back and his prayer is correct.
