Muwatta Imam Malik (Riwayat Yahya)

It is narrated from Abdullah al-Sanabahi that the Messenger of Allah, peace and blessings be upon him, said: "When a believing servant begins ablution and rinses his mouth, the sins exit from his mouth. Then when he washes his face, the sins exit from his face, until they exit from the places where the eyelashes grow, that is, from the eyelids. Then when he wipes his head, the sins exit from his head, until they exit from his two ears. Then when he washes his feet, the sins exit from his two feet, until they exit from the nails of his two feet. Then his walking towards the mosque, and the prayer, are separate—that is, their reward is distinct."
