The Messenger of Allah ﷺ used to say in his bowing and prostration, "Glorified, Most Holy, Lord of the angels and the Spirit."
أن رسول الله ﷺ كان يقول في ركوعه وسجوده: سبوح قدوس رب الملائكة والروح.
Muslim narrated it in the Book of Prayer (487) from Abu Bakr bin Abu Shayba, from Muhammad bin Bishr Abdi, from Saeed bin Abu Aruba, from Qatada, from Mutarrif bin Abdullah bin Shikhir, that Ayesha informed him, and he mentioned the hadith.
