Ruling 1184 — Prayer (Ṣalāh)

If a person doubts whether or not he has performed a recommended prayer, in the event that the prayer does not have a specific time for its performance, such as the Prayer of Jaʿfar al-Ṭayyār,[1] he must assume he has not performed it. The same applies if the recommended prayer does have a specific time for its performance, such as the daily nāfilah prayers, and before its time has expired one doubts whether or not he has performed it. However, if one doubts whether or not he has performed it after its time has expired, he must dismiss his doubt.
