The Duty of the Worshiper while Facing an Invalidating Doubt

Question: If during the prayer one of the doubts that invalidate the prayer occur to someone, can he leave the prayer immediately?
Answer: As a precaution, he cannot leave the prayer immediately, but he must think for a while so that doubt (probability of 50 percent) is fixed/established (i.e. he does not become confident nor is one side more probable), and then leaving the prayer is not objected.
