"Two words are light on the tongue, weigh heavily in the balance, they are loved by the Most Merciful One." - Prophet Muhammad ﷺ (Sahih Al-Bukhari I Sahih Muslim)

Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "(The following are) two words (sentences or utterances) that are very easy for the tongue to say, and very heavy in the balance (of reward), and most beloved to the Gracious Almighty (And they are): 

 : سُبحَانَ اللّهِ وَ بِحَمْدِهِ ، سُبحَانَ اللّهِ الْعَظِيمِ 

Subhan Allahi wa bi-hamdihi; Subhan Allahi-il-'Adhim"
