Abu Hurayrah (radhi-yAllaahu 'anhu) reported that the Messenger of Allaah (sal-Allaahu 'alayhe wa sallam) said: [There are] Two words, [which are] light on the tongue, heavy on the Scale and beloved to The Most Gracious:
سُبْحَانَ اللّٰهِ وَبِحَمْدِهِ، سُبْحانَ اللّٰهِ الْعَظِيْمِ
How perfect Allaah is and I praise Him. How perfect Allaah is, The Supreme.
Subhaanal-laahi wa bihamdihi, Subhaanal-laahil-'Adheem.
