question #2 Sahih Muslim 605c, Book 5, Hadith 203 : How does the practice of organizing in rows before the prayer leader begins relate to discipline in Islamic worship?

Abu Salama reported on the authority of Abu Huraira that when Iqama was pronounced for the Messenger of Allah (ﷺ), the people occupied their places in the rows before the Messenger of Allah (way peace be upon him) stood up at his place.
