question #1 Sahih Muslim 523f, Book 5, Hadith 12 : How does the concept of being aided by instilling fear in the hearts of enemies relate to the Prophet’s mission?

That is what Abu Huraira reported to us from the Messenger of Allah (ﷺ) and he narrated (some) ahadith one of which is that the Messenger of Allah (ﷺ) said: I have been helped by terror (in the hearts of enemies) and I have been given words which are concise but comprehensive in meaning.
