Aishah reported that the Prophet ﷺ used to say in his bowing and prostration, "Glorified, Most Holy, Lord of the angels and the Spirit."
أن النبي ﷺ كان يقول في ركوعه وسجوده: سبوح قدوس رب الملائكة والروح.
Muslim narrated it in the Book of Prayer (487) through several routes from Qatada, from Mutarrif bin Abdullah bin Shikhir, from Ayesha, and he mentioned it.
