Volume 6, Book 61, Number 577:
Narrated ‘Ali:
I heard the Prophet saying, “In the last days (of the world) there will appear young people with
foolish thoughts and ideas. They will give good talks, but they will go out of Islam as an arrow goes
out of its game, their faith will not exceed their throats. So, wherever you find them, kill them, for
there will be a reward for their killers on the Day of Resurrection.”
