Is the rak'ah valid for one who catches the imam while he is bowing?
Machine translationRead the Arabic original
The questioner : Shaykh, another question. Shaykh, if I missed the imam's recitation and then I am bowing while he is bowing, do I recite after him? Shaykh, does my bowing count as a rak'ah, or do I have to make it up?
The Shaykh: Repeat your question.
The questioner : If I left the imam while he was bowing, O Shaykh, and I did not leave the recitation behind him.
The Shaykh : Yes, regarding the validity of the rak'ah and the validity of the prayer.
The questioner : And the recitation of al-Fatihah, O Shaykh, why is it a pillar?
The Shaykh: May Allah guide you, you took the answer a second time.
The questioner : And upon you, peace.
The Shaykh : And you as well.
The questioner : Peace be upon you.
The Shaykh : And upon you be peace, and the mercy of Allah and His blessings.
The questioner : Did you understand this? No, the emirates.
The Shaykh : A whisper.
