Ruling 1428 — Prayer (Ṣalāh)

If a person recites Sūrat al-Ḥamd and the other surah thinking that the imam is in the third or fourth rakʿah, and before or after rukūʿ he realises that it was the first or second rakʿah, his prayer is valid. If he realises this during Sūrat al-Ḥamd or the other surah, it is not necessary that he complete them.
