Ibn Hibban

Sayyiduna Abdullah bin Zubair (may Allah be pleased with them both) narrates this statement from Sayyiduna Sufyan bin Abu Zuhair (may Allah be pleased with him): I heard the Prophet Muhammad (peace and blessings be upon him) say: "When Yemen is conquered, some people will come hastily, bringing their families and their servants (i.e., slaves) mounted with them, although if they had knowledge, Medina would have been better for them. When Sham is conquered, some people will come hastily, bringing their families and their followers (i.e., slaves and maidservants) mounted with them, although if they had knowledge, Medina would have been better for them. Then when Iraq is conquered, some people will come hastily, bringing their families and their servants (i.e., slaves and maidservants) mounted with them, although if they had knowledge, Medina the Illuminated would have been better for them."

The Shaykh says: The word «یبسون» means to come hastily.
