"I went out on a campaign with the Messenger of Allah ﷺ toward Najd. We confronted the enemy and formed ranks facing them. The Messenger of Allah ﷺ stood up and led us in prayer. Some of us stood with him and some of us faced the enemy. The Messenger of Allah ﷺ bowed and those who were with him bowed, and prostrated twice. Then they moved away and took the place of the others, and the other group who had not prayed came and he led them in bowing once and prostrating twice. Then the Messenger of Allah ﷺ said the salam and each of the Muslims stood up and bowed once, and prostrated twice individually." (Using translation from Nasāʾī 1539)   

«غَزَوْتُ مَعَ رَسُولِ اللَّهِ ﷺ غَزْوَةً قِبَلَ نَجْدٍ فَوَازَيْنَا الْعَدُوَّ وَصَافَفْنَاهُمْ» فَقَامَ رَسُولُ اللَّهِ ﷺ يُصَلِّي لَنَا فَقَامَ طَائِفَةٌ مِنَّا مَعَهُ وَأَقْبَلَ طَائِفَةٌ عَلَى الْعَدُوِّ فَرَكَعَ رَسُولُ اللَّهِ ﷺ بِمَنْ مَعَهُ رَكْعَةً وَسَجَدَ سَجْدَتَيْنِ ثُمَّ انْصَرَفُوا فَكَانُوا مَكَانَ الطَّائِفَةِ الَّتِي لَمْ تُصَلِّ وَجَاءَتِ الطَّائِفَةُ الَّتِي لَمْ تُصَلِّ فَرَكَعَ بِهِمُ النَّبِيُّ ﷺ رَكْعَةً وَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ رَسُولُ اللَّهِ ﷺ فَقَامَ كُلُّ رَجُلٍ مِنَ الْمُسْلِمِينَ فَرَكَعَ لِنَفْسِهِ رَكْعَةً وَسَجَدَ سَجْدَتَيْنِ  

[Machine] "The imam leads one group while another group faces the enemy, then he performs a prayer with those who are with him. The first group then joins their companions and they perform a prayer together, completing a separate prayer for themselves."  

«يُصَلِّي الْإِمَامُ بِطَائِفَةٍ وَطَائِفَةٌ مُوَاجِهَةُ الْعَدُوِّ فَيُصَلِّي بِالَّذِينَ مَعَهُ رَكْعَةً وَيَذْهَبُ هَؤُلَاءِ إِلَى مَصَافِّ أَصْحَابِهِمْ وَيَجِيءُ أُولَئِكَ فَيُصَلِّي بِهِمْ رَكْعَةً وَيَقْضُونَ رَكْعَةً لِأَنْفُسِهِمْ»
