question #1 Sahih Muslim 392a, Book 4, Hadith 30 : How important is it to follow the prayer practices of the Prophet Muhammad (ﷺ) as closely as possible?

Abu Huraira led prayer for them and recited takbir when he bent and raised himself (in ruku’ and sujud) and after completing (the prayer) he said: By Allah I say prayer which has the best resemblance with the prayer of the Prophet (ﷺ) amongst you.
