Explanation

This phrase is recited during ruku, the bowing position in prayer. It glorifies Allah and acknowledges His greatness while we humble ourselves.

Different phrases are said in different prayer positions. In sujud you say “Subhana Rabbiyal A’la” while in ruku you say “Subhana Rabbiyal Adhim.”

Each phrase reminds us of Allah’s attributes while our body shows physical submission.
