The Messenger of Allaah - may peace and blessings of Allaah be upon him – said :

Is one of you so weak that he cannot acquire a thousand good deeds everyday? So a questioner from amongst those sitting there asked him : How can anyone of us gain a thousand rewards?
He said: say :

Subhana allaahi
(Far is Allaah from imperfection)

a hundred times, so a thousand good deeds are written for him or a thousand sins are canceled for him.
