The Messenger of Allah said: "When the Iqamah is called for the prayer, do not come running. Come walking with tranquility. Whatever you catch up with, pray, and whatever you miss, complete it." (Using translation from Ibn Mājah 775)
"إذا أتيتم الصلاة فعليكم بالسكينةِ، ولا تأتوها وأنتم تَسْعَوْنَ، فما أدركتم فَصلُّوا وما فاتكم فَأَتِمُّوا" .
