Jubair (may Allah have mercy on him) says that I heard Abu Tha’labah (may Allah be pleased with him) saying, while he was in the city of Fustat during the caliphate of Muawiyah (may Allah be pleased with him), and Muawiyah (may Allah be pleased with him) had sent people for jihad to Constantinople: "By Allah! This Ummah will not be incapable for half a day. When you see, in the evening, the dining spread of a man and his household, then the conquest of Constantinople is near."
