Fath al-Rabbani

It is narrated from Sayyiduna Abdullah Sanabahi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When a servant performs ablution and rinses his mouth, the mistakes exit from his mouth; when he cleans his nose, the errors fall from his nose; when he washes his face, the sins are removed from his face, even to the extent that the sins come out from the roots of his eyelashes. Then when he washes his arms, the errors come out from his arms, even to the extent that they fall from beneath his fingernails. When he wipes his head and ears, the sins fall from his head, and (by washing the feet) the sins fall from beneath the toenails. Then his walking towards the mosque and performing the prayer is an additional virtue."
