Question:
The Honorable Shaykh, may Allah grant you success, says: If a man doubts while in the final tashahhud whether he recited al-Fatihah in his first rak'ah or did not, what is obligatory for him?
Answer:
If he doubts while in prayer whether he recited al-Fatihah or not, he must perform a rak'ah. He must perform a rak'ah and build upon certainty. If he doubts that he left out al-Fatihah, because he is in doubt about leaving out a pillar, he performs a rak'ah and prostrates for forgetfulness. His prayer is valid, as you heard, because whoever doubts that he left out a pillar, he has left it out.
