Are the prayers in which there was much doubt and for which the two prostrations of forgetfulness were performed considered valid, or must they be made up?

If a worshiper doubts during their prayer and performs what is required of them, their prayer is valid, and they are not obliged to repeat it, because mere doubt and prostration due to it do not invalidate the prayer. The doubt upon which one builds upon the minimum and performs the prostration of forgetfulness (sujud al-sahw) is that which occasionally afflicts the worshiper. However, for one who is constantly afflicted by doubt, even once a day, they must disregard it and build upon the maximum, and perform prostration after the salutation according to some jurists. If a person who doubts frequently builds upon the minimum and rectifies their prayer, their prayer is not invalidated, because they have returned to the original principle.
