Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings be upon him): "When you come for prayer, do not come running towards it, rather come in a state of calmness. Perform as much of the prayer as you catch, and complete what you have missed afterwards."
