The ruling on "Subhan Allah wa bihamdih" in ruku' and sujud

Question:
His saying: "Subhan Allah wa bihamdih"?

Answer:
In ruku' and sujud?
Q: Yes.
A: There is nothing wrong with it, but the well-known phrase is "Subhan Rabbi al-'Azeem." If one says "Subhan Allah wa bihamdih," it is permissible, just as the Prophet (peace and blessings be upon him) said.
Q: Subhan Allah al-'Azeem wa bihamdih?
A: There is nothing wrong with it, but leaving it out is better. One should say "Subhan Rabbi al-'Azeem, Subhan Rabbi al-'Azeem," because there is a concern regarding its authenticity among the scholars of hadith; its chains of narration are weak. However, if one says it, it causes no harm, because it is found in the phrase "Subhanaka Allahumma Rabbana wa bihamdika..." in an authentic hadith. So the matter is broad in this regard. In the authentic collections, it is narrated from Aisha (may Allah be pleased with her) that he used to frequently say in ruku' and sujud: "Subhanaka Allahumma Rabbana wa bihamdika, Allahumma ighfir li." This is in the authentic collections from Aisha (may Allah be pleased with her).
