It is narrated from Sayyiduna Nafi’ bin Utbah bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“You will fight the people of the Arabian Peninsula and Allah will grant you victory over them, then you will fight the people of Persia and Allah will grant you victory over them as well, then you will fight the Romans and Allah will grant you victory over them too, and then you will fight the Dajjal and Allah will grant you victory over him as well.”Sayyiduna Jabir (may Allah be pleased with him) says that this means the Dajjal will not emerge before the conquest of Rome.
