Al-Sa'ib bin Yazid (may Allah be pleased with him) said: I was lying down when suddenly a man was throwing pebbles at me. I raised my head, and it was Umar bin al-Khattab (may Allah be pleased with him), who said: Bring these two men to me. I brought them, and Umar (may Allah be pleased with him) asked: "Where have you come from, and who are you?" They said: "From Ta'if." He said: "If you had been from this city, I would have punished you severely; you are raising your voices in the Mosque of the Prophet."
