Abu Huraira (رضي الله عنه) reported that the Messenger of Allah (صلى الله عليه وسلّم) said, "When the Muslim - or believing - slave does wudu' and washes his face, every wrong thing at which his eyes have looked leaves with the water - or with the last drop of water. When he washes his hands, every wrong thing which his hands have touched leaves with the water - or with the last drop of water. When he washes his feet. every wrong thing to which his feet have walked leaves with the water – or with the last drop of water, until he emerges cleansed of sins."
[Muslim 1/148 and others]
Uthman ibn Affan (رضي الله عنه) said, "I saw the Messenger of Allah (صلى الله عليه وسلّم) do wudu like I am doing wudu now. Then he said, 'Anyone who does wudu' like that, will be forgiven his previous wrong actions, and his prayer and his walking to the mosque are an added bonus.'"
[Muslim 3/113]
What's next, a prayer machine that takes you through the positions automatically when you sit on it?
A hajj bike that does the tawaf for you and fires pebbles at the shaytan?
