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."

Narrated Ka`b bin Malik: During the lifetime of Allah's Apostle I asked Ibn Abi Hadrad in the mosque to pay the debts which he owed to me and our voices grew so loud that Allah's Apostle heard them while he was in his house. So he came to us after raising the curtain of his room. The Prophet said, "O Ka`b bin Malik!" I replied, "Labaik, O Allah's Apostle." He gestured with his hand to me to reduce the debt to one half. I said, "O Allah's Apostle have done it." Allah's Apostle said (to Ibn Hadrad), "Get up and pay it."
