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]'."[Al-Bukhari and Muslim].
