Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ka'b that he said: Soon a fire will emerge from Yemen which will drive people. In the morning, when they halt, it will halt with them at the same place, and wherever they stop to rest at noon, it will also stop with them there, and in the last part of the night when they travel, it will travel with them. When you hear about it, then go towards Syria.
