A man once went to Raabi'ah bint Isma'il al-'Adawiyyah, who was known by the titles, 'Mother of Goodness,' and, 'The Famous Worshipper.' He said, 'Indeed, I have perpetrated a great number of sins. If I repent, do you think that Allah will accept my repentence?" 

She said, "Woe unto you! Do you not see that He invites those who turn away from Him; then why wouldn't He accept the repentance of those who turn towards Him?"
