Riyad as-Salihin, Book 1, Hadith 129 (In-Book) ⓘ

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah said, "When a Muslim or a believer washes his face (in the course of Wudu'), every sin he has committed with his eyes is washed away from his face along with water, or with the last drop of water; when he washes his hands, every sin they wrought is erased from his hands with the water, or with the last drop of water; and when he washes his feet, every sin towards which his feet walked is washed away with water, or with the last drop of water, with the result that he comes out cleansed of all sins".[Muslim].

الثالث عشر‏:‏ عنه أن رسول الله صلى الله عليه وسلم قال‏:‏ ‏ "‏ إذا توضأ العبد المسلم، أو المؤمن فغسل وجهه خرج من وجهه كل خطيئة نظر إليها بعينيه مع الماء، أو آخر قطر الماء، فإذا غسل رجليه خرجت كل خطيئة مشتها رجلاه مع الماء أو مع آخر قطر الماء حتى يخرج نقياً من الذنوب‏" ‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
