The poet, Abu Nawaas says:
As I ponder over my sins, their number is vast
But the mercy of my rabb is even vaster
My hope in my acts is naught
But I am very hopeful of the mercy of my rabb
For he is my protecting friend, who has created me
And I am his slave, humble and confessing
So if he forgives, it will be through his mercy
But if matters are otherwise, what can I do??
