What does your yawning or sneezing in Salah lead to? – (Hanbali Fiqh)

Answered according to Hanbali Fiqh by TheHanbaliMadhhab.com

❝One common error that invalidates the prayer, is that a person yawns or sneezes during the Salah, while missing out some letters or mispronouncing them from Surat al-Fatiha [or other obligatory recitation], and then continuing without repeating those missed parts. As for the one praying behind the Imam, then this does not invalidate the prayer according to our madhhab, because the recitation of the Imam counts for his recitation. However, he will have missed the complete reward for reciting it.❞

— Shaykh Dr. Karim Hilmi al-Hanbali
