There are many benefits of Wudhu.
Prophet Muhammad ﷺ said: “He who performs the Wudu perfectly (according to Sunnah), his sins will depart from his body, even from under his nails.” [Sahih Muslim]
The Messenger of Allah ﷺ said, “Whoever can increase the area of his radiance should do so.” [Sahih Bukhari and Sahih Muslim]
It is recorded in Ibn Majaah**** that the Prophet said ﷺ: “… and no one preservers their wudu except a Believer.”
The Prophet ﷺ said: “The adornment of the believer (in Jannah) will reach the places where the water of Wudu reaches (his body).” [Sahih Muslim]
