Question:
What is the ruling on the prayer of one who did not say the supplication of prostration, "Subhana Rabbi al-A'la" (Glory be to my Lord, the Most High), because he forgot?
Answer:
If he leaves out an obligatory part of the prayer, he has to perform a rak'ah. So if he left it out in the prostration, meaning he did not say "Subhana Rabbi al-A'la" in any of the prostrations, he has to perform a rak'ah. Yes.
