There is no believing servant except that he has a sin which he commits from time to time

From Ibn 'Abbaas (radiyallaahu 'anhumaa) who said that Allaah's Messenger (salallaahu 'alaihi wa'sallam) said: There is no believing servant except that he has a sin which he commits from time to time, or a sin in which he persists in and does not abandon until he leaves this world. Indeed the Believer was created as one who is frequently tried and tested, who often repents (then) forgets. When he is admonished he accepts the admonition. Reported by at-Tabaraanee in al-Mu'jamul Kabeer (no. 11,810) its chain of narration is hasan.
