It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When you come for prayer, do not come running, but come walking (at your normal pace), and let there be calmness and tranquility upon you. Then whatever part of the prayer you catch with the Imam, perform it, and whatever you miss, complete it afterwards."
