What is required of one who prays alone and doubts that he did not recite al-Fatihah?

Question:
Honorable Shaykh, may Allah grant you success. He says: When I pray alone, sometimes, and when I bow, I doubt that I did not recite al-Fatihah. So, do I count this rak'ah, or is this doubt unfounded?

Answer:
If this is repeated with you or is waswas (whispers of Satan), leave it. But if you have no waswas, you have no waswas, then this is what you exit from the pillar except with certainty. So you recite al-Fatihah, you recite al-Fatihah, then you recite what comes after it and you complete your prayer. Yes.
