سنن النسائي

'Amr bin 'Abasah said: "I said: 'O Messenger of Allah! How is Wudu' done?' He said: 'As for Wudu', when you perform Wudu', and you wash your hands to clean them, your sins come out from between your fingers and fingertips. When you rinse your mouth and nostrils, and wash your face and hands up to the elbows, and wipe your head, and wash your feet up to the ankles, you are cleansed of all your sins. When you prostrate your face to Allah, may He be exalted, you emerge from your sins like the day your mother bore you.'" Abu Umamah said: "I said: 'O 'Amr bin 'Abasah! Look at what you are saying! Was all of that given in one sitting? He said: 'By Allah, I have grown old, my appointed time is near and I am not so poor that I should tell lies about the Messenger of Allah (ﷺ). I heard it with my own ears and understood it in my heart from the Messenger of Allah.'"
