It is narrated from Hazrat Abu Qatadah (may Allah be pleased with him) that once we were praying with the Noble Prophet (peace and blessings be upon him) when we heard the sound of some people running. The Noble Prophet (peace and blessings be upon him) called them after finishing the prayer and asked, "What was the matter?" They replied, "O Messenger of Allah! We wanted to join the prayer quickly." The Noble Prophet (peace and blessings be upon him) said, "Do not do so. When you come for prayer, make calmness and tranquility obligatory upon yourselves. Pray as much as you catch, and complete what you miss."
