Sayyiduna Sufyan bin Abi Zuhair (may Allah be pleased with him) narrated that I heard the Messenger of Allah (peace and blessings be upon him) say: "When Yemen is conquered, some people will drive their mounts fast and will bring their families and those who obey them, mounting them, and will take them from Madinah (back) to Yemen. If only they knew that Madinah is better for them. And when Sham is conquered, some people will drive their mounts fast and will bring their families and all those who obey them, and will take them (back) to Sham. If only they knew that Madinah is better for them. And when Iraq is conquered, some people will drive their mounts fast and will bring their families and those who obey them, and will take them (back) to Iraq. If only they knew that Madinah is better for them."
