Sahih Bukhari Volume 008, Book 075, Hadith Number 379.
Narated By 'Aisha : The Prophet used to say, "O Allah! I seek refuge with You from laziness and geriatric old age, from all kinds of sins and from being in debt; from the affliction of the Fire and from the punishment of the Fire and from the evil of the affliction of wealth; and I seek refuge with You from the affliction of poverty, and I seek refuge with You from the affliction of Al-Mesiah Ad-Dajjal. O Allah! Wash away my sins with the water of snow and hail, and cleanse my heart from all the sins as a white garment is cleansed from the filth, and let there be a long distance between me and my sins, as You made East and West far from each other."
