Umar b. al-Khattab was making his way through Madina at night when he heard a man singing in his home. He jumped over the fence and said, ?O Enemy of Allah! Did you think that Allah would conceal you while you disobey Him?!' The man retorted, 'What about you, O Commander of the faithful? Do not hasten to Punish me, for if I disobeyed Allah once, you did so three times. He has said, 'Do not spy,' and you did spy [on me]. He also said, 'Enter the homes from their doors,' but you jumped over my fence and without my permission. And Allah, the Exalted, says, 'Do not enter homes that are not yours until you are invited in and until you greet their owners.' 'Umar said, 'Is there any good in you, if I decide to pardon you?' The man said, 'Yes.' Then 'Umar pardoned him and departed.'
