“Gog and Magog will come down. As Almighty Allah says, ‘They will flow down from high places,’ and infect people, and Muslims will flee from them and retire to the cities and their castles and will take their animals with them. Gog and Magog will drink the waters of the earth and when they come to a river they will drink it dry, and those who come after them will say, ‘There used to be water here.’
