Which is more correct in Rukūʿ: saying "Subḥāna Rabbī al-ʿAẓīm wa bi-ḥamdihi" (Glory be to my Lord, the Most Great, and with His praise) or "Subḥāna Rabbī al-ʿAẓīm" (Glory be to my Lord, the Most Great) only? And similarly in Sujūd: is it more correct to say "Subḥāna Rabbī al-Aʿlā wa bi-ḥamdihi" (Glory be to my Lord, the Most High, and with His praise) or "Subḥāna Rabbī al-Aʿlā" (Glory be to my Lord, the Most High) only?

The utterance "Subhan Rabbi al-Azeem" (Glory be to my Lord, the Most Great) in bowing (ruku') and "Subhan Rabbi al-A'la" (Glory be to my Lord, the Most High) in prostration (sujud) is unanimously agreed upon as authentic. As for the addition of "(wa bihamdihi)" (and with His praise) to both, some jurists have permitted it while others have prohibited it. The correct view is that it is a proven addition, which the Prophet, peace and blessings be upon him, frequently uttered, even though most of the soundest narrations restrict it to the glorification without this addition. A number of hadith scholars, including Al-Albani, have authenticated this addition. In conclusion, this addition is sound and proven, and it is recommended to sometimes include it and sometimes omit it, in adherence to the Sunnah.
