What is the ruling on pausing and repeating a word in Al-Fatihah without making a mistake, and is that considered an intentional error?

This act stems from whisperings (waswas), and whoever is afflicted by it must strive against himself to abandon and disregard it. He should recite naturally, without affectation, pay no attention to the devil's whisperings, and continue with his prayer until Allah grants him healing. If this act occurs due to waswas, it is not considered an intentional error in recitation (laḥn). However, the one afflicted by waswas must strive to cure this ailment.
