Dua' by Hasan al-Basri - Salaam and Greetings of Peace:

"O Allah, I seek your forgiveness for every sin for which I presented
my repentance before You; and regarding which I stood before You
swearing an oath in Your name and called Your friends from among Your
servants to be my witnesses – that I would never return to
disobeyingYou.
But when Satan with his cunning tempted me to return to it; and Your
forsaking me [due to Your anger over my impiety] caused me to
[despairingly] waver toward it; and my lower self invited me to
disobey You once more; I hid myself in shame from Your servants, but
openly and daringly committed sins before You, though I knew full well
that no covering nor any closed door could conceal me from You and no
veil could hide me from Your sight.
I still defied You by disobediently doing what You had prohibited to
me;but [despite my iniquity], You did not remove Your covering from
me, but rather treated me equal toYour pious servants, as though I had
always been an obedient servant and swift to fulfill Your every
command and fearful of Your warnings.
I remained obscure in front of Your servants, andnone besides You knew
my secret. You did not single me out from Your servants with a mark of
disgrace, but instead showered upon me blessings like theirs; and with
this You distinguished me over them as though I were, in Your sight,
of a status like theirs. All this was owing only of Your forbearance
and abundant blessings – generous grace from You to me. For You then,
O my Lord, belongs all praise.
I ask from You, O Allah, just as You have covered my evil deeds in
this world, that You do not humiliate me with them on the Day of
Judgment. Forgive my sins, O Most Merciful of the merciful!"
- One of the most eloquent of the seventy prayers in the book Prayers
for Forgiveness by Hasan al-Basri
