question #1 Sahih Muslim 523b, Book 5, Hadith 8 : What is the significance of concise and comprehensive speech in the teachings of the Prophet Muhammad (ﷺ)?

The Messenger of Allah (ﷺ) said: I have been commissioned with words which are concise but comprehensive in meaning; I have been helped by terror (in the hearts of enemies): and while I was asleep I was brought the keys of the treasures of the earth which were placed in my hand. And Abfi Huraira added: The Messenger of Allah (ﷺ) has left (for his heavenly home) and you are now busy in getting them.
