Sahih Bukhari Volume 8, Book 76, Hadith Number 474.

Narated By ‘Aisha : The Prophet said, “Do good deeds properly, sincerely and moderately, and receive good news because one’s good deeds will not make him enter Paradise.” They asked, “Even you, O Allah’s Apostle?” He said, “Even I, unless and until Allah bestows His pardon and Mercy on me.”
