O He who gives "much" in return of "very little" (good deeds)!
This is a part of a du"a (prayer/supplication) recommended to be recited after each daily prayer during the month of Rajab. Everyone may have their own interpretation of this. One night, while reciting this du"a, I was thinking that for me the "much" is Allah"s blessing to be a servant at the Holy Shrine of Imam Reza (AS), and the "very little" is my own deeds.
