Mishkat al-Masabih #141

Abu Musa reported God's messenger as saying, “I and the message with which God has entrusted me are just like a man who came to a people and said, "I have seen the army with my own eyes, and I am a simple warner, so flee, flee.' A section of his people obeyed him, and setting off at nightfall, went away without hurry and escaped. But a section of them did not believe him and stayed where they were, and the army attacked them at dawn, destroying and extirpating them. That is a comparison with those who obey me and follow my message, and with those who disobey me and disbelieve the truth I have brought.” (Bukhari and Muslim.)
