When the call is made for prayer come to it walking with tranquillity, and pray what you are in time for, and complete what you have missed.
Sahih Muslim Book 5, Hadith 196
← Previous Hadith When the words of Iqama are pronounced, do not come to (prayer) running, but go with tranquillity, and pray what you are in time for, and complete (what you have missed) for when one of you is preparing for prayer he is in fact engaged in prayer.

Sahih Muslim Book 5, Hadith 195 Next Hadith → The Messenger of Allah (ﷺ) said: When the words of Iqama are pronounced, none of you should run to it (to join the prayer) but walk with tranquillity and dignity, and pray what you are in time for and complete what has gone before (what the Imam has completed).
