There's a story I've at least once saying that during his Caliphate 'Omar ibn al-Khattab unmasked some people drinking alcohol in secrete -at night- when he wanted accused them for committing a sin they answered we have committed a single sin while you've committed three:
- You didn't ask for permission before entering our house while Allah says:
O you who have believed, do not enter houses other than your own houses until you ascertain welcome and greet their inhabitants. That is best for you; perhaps you will be reminded. (24:27)
- You didn't come from the door, while Allah says:
... And enter houses from their doors. And fear Allah that you may succeed. (2:189)
- and finally you spied us, while Allah says:
O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy or backbite each other. ... (49:12)
Where or in which book does this story appear is there any source for it?
Is this story authentic?
