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). (Using translation from Muslim 602d)
قَالَ رَسُولُ اللهِ ﷺ إِذَا ثُوِّبَ بِالصَّلَاةِ فَلَا يَسْعَى إِلَيْهَا أَحَدُكُمْ وَلَكِنْ لِيَمْشِ وَعَلَيْهِ السَّكِينَةُ وَالْوَقَارُ صَلِّ مَا أَدْرَكْتَ وَاقْضِ مَا سَبَقَكَ
