The Prophet ﷺ said, "When you hear the Iqama, proceed to offer the prayer with calmness and solemnity and do not make haste. And pray whatever you are able to pray and complete whatever you have missed. (Using translation from Bukhārī 636)
"إذا سمعتم الإِقَامَةَ فامْشُوا إلى الصلاةِ، وعليكم بالسكينِة والوقارِ ولا تُسْرِعوا، فما أدركتم فَصَلّوا وما فاتكم فأتِمُّوا".
