Abu Hurairah (May Allah be pleased with him) reported

The Messenger of Allah (ﷺ) said, "There are two statements that are light for the tongue to remember, heavy in the Scales and are dear to the Merciful: 'Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim [Glory be to Allah and His is the praise, (and) Allah, the Greatest is free from imperfection]'."
