Abu Hurairah reported: "The Messenger of Allah (pbuh) 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-Allahi-Azim. (Glory be to Allah and His is the praise, (and) Allah, the Greatest is free from imperfection)'." (Al-Bukhari and Muslim)
