Hadith Qudsi 34

O son of Adam, so long as you call upon Me & ask of Me, I shall forgive you for what you have done & I shall not mind. O son of Adam, were your sins to reach the clouds of the sky & were you then to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth & were you then to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great at it.
