It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) say: "Soon a man from Banu Umayyah will become ruler in Egypt. Then his rule will be overpowered, or it will be taken from him. Then he will flee to the Romans, and the Romans will come against the people of Islam, and that will be the first of the great battles."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) only with this chain; Ibn Lahi'ah (may Allah have mercy on him) is alone in narrating it."
