Gratitude

It is related that Abu 'Uthman was once riding in the street when a pot of ashes was thrown down upon him. He dismounted, and prostrated himself to God in gratitude, and then brushed the ashes from his clothes without saying a word. 'Shall you not rebuke them?' he was asked, but he replied, 'A man who deserves hellfire but receives only ashes cannot fairly be angry'.
