The Messenger of Allah said: "Whoever performs ablution and rinses his mouth and nose, his sins will exit through his mouth and nose. When he washes his face, his sins will exit from his face, even from beneath his eyelids. When he washes his hands, his sins will exit from his hands. When he wipes his head, his sins will exit from his head, and even from his ears. When he washes his feet, his sins will exit from his feet, even from beneath his toenails. Then his prayer and walking towards the mosque will earn extra merit for him." (Using translation from Ibn Mājah 282)
"إذَا توضَّأ العبدُ المؤمنُ فتمضمضَ خرجتِ الخطايا منْ فيِهِ، فإِذَا استنْثَرَ خرجت الخطايا من أنْفِهِ، فإِذَا غسل وجهَهُ خرجَتِ الخطايَا منَ وجهِهِ، حتى يخرجَ
منْ تحتِ أشْفارِ عينَيه، فإِذا غسلَ يدَيه خرجت الخطايا من يديه، حتى يخرجَ من تحتِ أظفار يديه، فإِذا مسحَ برأسِه خرجتِ الخطايا من رأَسِه، حتى يخرجَ من أُذنيه، فإِذا غسل رجليه خرجت الخطايا من رجليه حتى تخرجَ من تحتِ أظفارِ رجليه، ثم كانَ مشيُه إلى المسجدِ وصلاتُه نافلةً لهُ".
