Abdullah b. Abu Qatada reported on the authority of his father: 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.
