question #1 Sahih Muslim 207a, Book 1, Hadith 412 : What is the significance of the Prophet Muhammad’s role as a warner to his people?

When this verse was revealed:” And warn thy nearest kindred,” the Messenger of Allah (ﷺ) set off towards a rock of the hill and ascended the highest of the rocks and then called: 0 sons of ‘Abd Manaf! I am a warner; my similitude and your similitude is like a man who saw the enemy and went to guard his people, but, being afraid they might get there before him, he shouted: Be on your guard!
