وعنه قال: رأيت رسول الله صلى الله عليه وسلم يتوضأ مثل وضوئي هذا ثم قال: «من توضأ هكذا، غفر له ما تقدم من ذنبه، وكانت صلاته ومشيه إلى المسجد نافلة»
I saw the Messenger of Allah (sallallahu alayhi wa sallam) 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.”.
