Supplication for redemption

O Allah, I have greatly wronged myself and no one forgives sins but You. So, grant me forgiveness and have mercy on me. Surely, you are Forgiving, Merciful. Allaahumma ‘innee dhalamtu nafsee dhulman katheeran, wa laa yaghfiruth-thunooba ‘illaa ‘Anta, faghfir lee maghfiratan min ‘indika warhamnee ‘innaka ‘Antal-Ghafoorur-Raheem. Al-Bukhari 8/168, Muslim 4/2078.
