question #1 Sahih Muslim 605b, Book 5, Hadith 202 : What actions should be taken if a person needs to perform a ritual purification before prayer?

Iqama was pronounced. ant the people had formed themselves into rows. The Messenger of Allah (ﷺ) came out and stood at his place, and then pointed out with his hand that we should stand at our places. He then went away and took a bath and water trickled from his head and then led them in prayer.
