Sahih Adab al-Mufrad

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that he said: Among the supplications of the Prophet, peace and blessings be upon him, is: «اللهم اغفر لي ما قدمت وما أخرت، وما أسررت وما أعلنت، وما أنت أعلم به مني، إنك أنت المقدم والمؤخر، لا إله إلا أنت» "O Allah! Forgive all my sins, those I committed earlier and later, those I committed secretly and openly, and those You know better than I do. You are the One Who brings forward and the One Who delays. There is no deity except You."
