Abu Qabeel said: I heard Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) say: We were sitting around the Messenger of Allah (peace and blessings be upon him) writing, when suddenly the Messenger of Allah (peace and blessings be upon him) was asked: Which city will be conquered first, Constantinople or Rome? The Noble Prophet (peace and blessings be upon him) replied: "No, the city of Heraclius will be conquered first." (That is, Rome).
