Sufyan bin Abu Zuhair (may Allah be pleased with him) says: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "(In the future) Yemen will be conquered, and there will be some people who will drive their mounts fast and will take their families and those who obey them from Madinah to Yemen, even though Madinah would be better for them if they understood. And Sham will be conquered, and there will be some people who will drive their mounts fast and will take their families and those who obey them from Madinah to Sham, even though Madinah would be better for them if they understood. And Iraq will be conquered, and there will be some people who will drive their mounts fast and will take their families and those who obey them from Madinah to Iraq, even though Madinah would be better for them if they understood."
