There are two words that are light on the tongue, heavy on the scale, and dear to the Most Merciful

The Prophet (may Allah's peace and blessings be upon him) told about two words that the tongue utters without effort and in any condition, they bring great reward when weighed on the scale, and the Most Merciful Lord loves them: Glory be to Allah, the Majestic; glory and praise be to Allah. This is because these two words contain attributes of greatness and perfection of Allah Almighty and exalting Him far above defects and imperfections.
