I heard the Messenger of Allah ﷺ saying: When the Iqama has been pronounced for prayer, do not go running to it, but go walking in tranquillity and pray what you are in time for, and complete what you have missed.  

عَنِ النَّبِيِّ ﷺ ح قَالَ وَحَدَّثَنِي مُحَمَّدُ بْنُ جَعْفَرِ بْنِ زِيَادٍ أَخْبَرَنَا إِبْرَاهِيمُ يَعْنِي ابْنَ سَعْدٍ عَنِ الزُّهْرِيِّ عَنْ سَعِيدٍ وَأَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ ح قَالَ وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى وَاللَّفْظُ لَهُ أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ قَالَ أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّ أَبَا هُرَيْرَةَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا أُقِيمَتِ الصَّلاَةُ فَلاَ تَأْتُوهَا تَسْعَوْنَ وَأْتُوهَا تَمْشُونَ وَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ فَصَلُّوا وَمَا فَاتَكُمْ فَأَتِمُّوا  

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.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا ثُوِّبَ لِلصَّلاَةِ فَلاَ تَأْتُوهَا وَأَنْتُمْ تَسْعَوْنَ وَأْتُوهَا وَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ فَصَلُّوا وَمَا فَاتَكُمْ فَأَتِمُّوا فَإِنَّ أَحَدَكُمْ إِذَا كَانَ يَعْمِدُ إِلَى الصَّلاَةِ فَهُوَ فِي صَلاَةٍ  

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.  

عَنْ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا نُودِيَ بِالصَّلاَةِ فَأْتُوهَا وَأَنْتُمْ تَمْشُونَ وَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ فَصَلُّوا وَمَا فَاتَكُمْ فَأَتِمُّوا  

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).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا ثُوِّبَ بِالصَّلاَةِ فَلاَ يَسْعَ إِلَيْهَا أَحَدُكُمْ وَلَكِنْ لِيَمْشِ وَعَلَيْهِ السَّكِينَةُ وَالْوَقَارُ صَلِّ مَا أَدْرَكْتَ وَاقْضِ مَا سَبَقَكَ  

While we said our prayer with the Messenger of Allah ﷺ he heard tumult. (At the end of the prayer) he (the Holy Prophet) said: What is the matter with you? They said: We hastened to prayer. He (the Holy Prophet) said: Don't do that; when you come for prayer, there should be tranquillity upon you. Pray (along with the Imam) what you can find and complete what preceded you.  

أَخْبَرَهُ قَالَ بَيْنَمَا نَحْنُ نُصَلِّي مَعَ رَسُولِ اللَّهِ ﷺ فَسَمِعَ جَلَبَةً فَقَالَ مَا شَأْنُكُمْ قَالُوا اسْتَعْجَلْنَا إِلَى الصَّلاَةِ قَالَ فَلاَ تَفْعَلُوا إِذَا أَتَيْتُمُ الصَّلاَةَ فَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ فَصَلُّوا وَمَا سَبَقَكُمْ فَأَتِمُّوا  

This hadith has been narrated by Shaiban with the same chain of transmitters  

حَدَّثَنَا شَيْبَانُ بِهَذَا الإِسْنَادِ
