صحيح مسلم

Abu Musa reported Allah's Messenger (ﷺ) as saying: The similitude of mine and of that with which Allah sent me is that of a person who came to us and said: O people, I have seen an army with my eyes and I am a plain warner (and issue you warning) that you should immediately manage to find an escape. A group of people from amongst them paying heed (to his warning) fled to a place of protection and a group amongst them belied him and the morning overtook them in their houses and the army attacked them and killed them and they were routed. And that is the similitude of the one who obeyed me, followed with which I had been sent and the similitude of the other is of one who disobeyed and belied me and the Truth with which I have been sent.
