“When a muslim, or a beliver washes his face (in the course of Wudhu), every sin which he committed with his eyes, will be washed away from his face withwater, or with last drop of water; when he washes his hands, every sin which he committed by his hands will be effaced from his hands with the water, or with last drop of water;and when he washes his feet, every sin his feet committed will be washed away with the water, or with last drop of water;until he finally emerges cleansed of all his sins.” (Sahih Muslim)
