Sufyan b. Abu Zuhair told of hearing God’s messenger say, "The Yemen will be conquered and- people will come driving their camels gently, removing their families and those who are under their authority, but Medina would be best for them if they only knew. Syria will be conquered and people will come driving their camels gently, removing their families and those who are under their authority, but Medina would be best for them if they only knew. ‘Iraq will be conquered and people will come driving their camels gently, removing their families and those who are under their authority, but Medina would be best for them if they only knew.” Bukhari and Muslim.
