It is narrated from Hazrat Nafi' bin Utbah (may Allah be pleased with him) that the Prophet said: You will fight against the people of the Arabian Peninsula and Allah will grant you victory over them. Then you will fight against the people of Persia and Allah will grant you victory over them as well. Then you will fight against the people of Rome and Allah will grant you victory over them as well. Then you will fight against the Dajjal and Allah will grant you victory over him as well.
