question #3 Sahih Muslim 603a, Book 5, Hadith 198 : What guidance does the Prophet (ﷺ) provide regarding hastening to join the prayer?

While we said our prayer with the Messenger of Allah (ﷺ) he heard tumult. (At the end of the prayer) he (the Holy Prophet) said: What is the matter with you? They said: We hastened to prayer. He (the Holy Prophet) said: Don’t do that; when you come for prayer, there should be tranquillity upon you. Pray (along with the Imam) what you can find and complete what preceded you.
