'Uthman bin 'Affan (May Allah be pleased with him) reported:
I saw the Messenger of Allah (ﷺ) performing Wudu' the way I have just done it and said, "He who performs Wudu' like this, his previous sins will be forgiven and his Salat and walking to the mosque will be considered as supererogatory act of worship."[Muslim].
