Sahih al-Bukhari 6482
Narrated Abu Musa:
Allah's Messenger (ﷺ) said. "My example and the example of the message with which Allah has sent me is 
like that of a man who came to some people and said, "I have seen with my own eyes the enemy 
forces, and I am a naked warner (to you) so save yourself, save yourself! A group of them obeyed him 
and went out at night, slowly and stealthily and were safe, while another group did not believe him 
and thus the army took them in the morning and destroyed them."
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ مَثَلِي وَمَثَلُ مَا بَعَثَنِي اللَّهُ كَمَثَلِ رَجُلٍ أَتَى قَوْمًا فَقَالَ رَأَيْتُ الْجَيْشَ بِعَيْنَىَّ، وَإِنِّي أَنَا النَّذِيرُ الْعُرْيَانُ فَالنَّجَا النَّجَاءَ‏.‏ فَأَطَاعَتْهُ طَائِفَةٌ فَأَدْلَجُوا عَلَى مَهْلِهِمْ فَنَجَوْا، وَكَذَّبَتْهُ طَائِفَةٌ فَصَبَّحَهُمُ الْجَيْشُ فَاجْتَاحَهُمْ ‏"‏‏.‏
