"Ali (رضي الله عنه) said: When I narrate to you from the Messenger of Allah (ﷺ), it would be dearer to me to be thrown down from the sky than to tell lies about him. But if I narrate to you from anyone else, then I am a warrior and war is deceit. I heard the Messenger of Allah (ﷺ) say: "There will emerge at the end of time people who are young in age and immature. They will speak like the best of people but their faith will go no deeper than their throats. Wherever you encounter them, kill them, for killing them brings to the one who kills them reward with Allah on the Day of Resurrection."
