Abdullah bin Abu Qatadah narrates from his father: Once we were offering prayer behind the Prophet Muhammad (peace be upon him). During the prayer, he heard the sound of some people hurrying. When he completed the prayer, he called them and asked: What happened to you? They replied: O Messenger of Allah (peace be upon him)! We were hurrying to join the prayer. The Prophet Muhammad (peace be upon him) said: Do not be hasty. When you come to the prayer, come calmly. Whatever part of the prayer you catch, perform it, and whatever you have missed, complete it (afterwards).
