'Affan narrated to us, Abu 'Awanah narrated to us, 'Abd al-Malik ibn 'Umayr narrated to us, from Jabir ibn Samurah, from Nafi' ibn 'Utbah ibn Abi Waqqas, that he heard the Prophet, peace and blessings of Allah be upon him, saying: "You will invade the Arabian Peninsula, and Allah will grant you victory. Then you will invade Persia, and Allah will grant you victory. Then you will invade the Romans, and Allah will grant you victory. Then you will invade the Dajjal, and Allah will grant you victory."
