Is the prayer valid if one feels a movement in the lower abdominal muscles—indicating the emission of wind—while moving from prostration to standing, based on the Hadith: "He should not leave until he hears a sound or finds a smell"?

If a worshiper doubts that wind has been emitted from him during prayer, he should not discontinue his prayer until he is certain of the impurity by hearing a sound or smelling an odor. He should complete his prayer, and there is nothing upon him. However, if he is certain that wind has been emitted, he must repeat his ablution and prayer. This is from the whispers of Satan to distract the Muslim from his prayer, so one should not respond to these whispers except with certainty.
