question #3 Sahih Muslim 867b, Book 7, Hadith 56 : What can be learned from the way the Prophet Muhammad (ﷺ) raised his voice during sermons?

I heard Jabir b. ‘Abdullah saying that in the sermon of the Messenger of Allah (ﷺ) he praised Allah, lauded Him (and subsequently said [other words] and raised his voice, and the rest of the hadith is the same).
