Sayyiduna Abu Umamah al-Bahili (may Allah be pleased with him) states: Once we were sitting with the Prophet (peace and blessings be upon him). The people mentioned Sham and the Romans who were there, and the Prophet (peace and blessings be upon him) said: "Soon you will overcome Sham, and you will reach a fortress on its sea called Anafah. On the Day of Resurrection seventy thousand martyrs will be raised from there."
Al-Tabarani recorded it, and its chain contains a narrator whom I do not know.
