question #1 Sahih Muslim 699b, Book 6, Hadith 36 : What is the significance of following the example of the Prophet Muhammad (ﷺ) in religious practices?

I heard ‘Abdullah b. al-Harith say: ‘Abdullah b. ‘Abbas addressed us on a rainy day, and the rest of the hadith is the same, but he made no mention of Jumu’a prayer, and added: He who did it (who commanded us to say prayer in our houses), i. e. the Messenger of Allah (ﷺ), is better than I.
