Narrated Al-Sa'ib bin Yazid: I was standing in the mosque and somebody threw a gravel at me. I looked and found that he was `Umar bin Al-Khattab. He said to me, Fetch those two men to me. When I did, he said to them, Who are you? (Or) where do you come from? They replied, We are from Ta'if. `Umar said, Were you from this city (Medina) I would have punished you for raising your voices in the mosque of Allah's Apostle.
