أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى بِهِمْ صَلاَةَ الْخَوْفِ فَقَامَ صَفٌّ بَيْنَ يَدَيْهِ وَصَفٌّ خَلْفَهُ صَلَّى بِالَّذِينَ خَلْفَهُ رَكْعَةً وَسَجْدَتَيْنِ ثُمَّ تَقَدَّمَ هَؤُلاَءِ حَتَّى قَامُوا فِي مَقَامِ أَصْحَابِهِمْ وَجَاءَ أُولَئِكَ فَقَامُوا مَقَامَ هَؤُلاَءِ وَصَلَّى بِهِمْ رَسُولُ اللَّهِ ﷺ رَكْعَةً وَسَجْدَتَيْنِ ثُمَّ سَلَّمَ فَكَانَتْ لِلنَّبِيِّ ﷺ رَكْعَتَانِ وَلَهُمْ رَكْعَةٌ  

[Machine] "The Messenger of Allah, peace be upon him, performed the prayer of fear with a group of his companions. He arranged them in rows and prayed alongside them, matching the movements of the enemy. Then they went towards the enemy, and the enemy came towards them, and they all prayed with the Prophet, peace be upon him, a unit of prayer. Then he greeted them."  

«صَلَّى رَسُولُ اللَّهِ ﷺ صَلَاةَ الْخَوْفِ بِذِي قَرَدٍ فَصَفَّ خَلْفَهُ صَفًّا وَصَفًّا مُوَازِيَ الْعَدُوِّ فَصَلَّى مَعَهُ رَكْعَةً ثُمَّ ذَهَبُوا إِلَى مَصَافِّ أُولَئِكَ وَجَاءَ أُولَئِكَ إِلَى مَصَافِّ هَؤُلَاءِ وَصَلَّوْا مَعَ النَّبِيِّ ﷺ رَكْعَةً ثُمَّ سَلَّمَ عَلَيْهِمْ»

So, the Prophet ﷺ performed two units of prayer and each group performed one unit of prayer."  

«صَلَّى رَسُولُ اللَّهِ ﷺ وَصَفٌّ خَلْفَهُ وَصَفٌّ بِإِزَاءِ الْعَدُوِّ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ ذَهَبُوا إِلَى مَصَافِّ إِخْوَانِهِمْ وَجَاءَ الْآخَرُونَ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ سَلَّمَ فَكَانَ لِلنَّبِيِّ ﷺ رَكْعَتَانِ وَلِكُلِّ طَائِفَةٍ رَكْعَةٌ»

«قَامَ رَسُولُ اللهِ فَصَلَّى بِهِمْ فَقَامَ صَفٌّ خَلْفَهُ وَصَفٌّ مُوَازٍ الْعَدُوَّ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ ذَهَبَ هَؤُلَاءِ إِلَى مَصَفِّ هَؤُلَاءِ وَجَاءَ هَؤُلَاءِ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ انْصَرَفَ»

صَلَّى رَسُولُ اللهِ ﷺ صَلَاةَ الْخَوْفِ فَصَفَّ صَفًّا خَلْفَهُ وَصَفًّا مُوَازِي الْعَدُوِّ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ ذَهَبَ هَؤُلَاءِ إِلَى مَصَافِّ هَؤُلَاءِ وَجَاءَ هَؤُلَاءِ إِلَى مَصَافِّ هَؤُلَاءِ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ سَلَّمَ  

"صَلَّى رَسُولُ الله ﷺ صَلاةَ الْخَوْفِ بِذِى قَرَدَ فَصَفَّ صَفًّا خَلفَهُ، وَصَفًّا مُوَازىَ الْعَدُوِّ، فَصَلَّى بِهمْ رَكعَةً، ثُمَّ سَلَّمَ عَلَيْهِمْ جَمِيعًا، ثُمَّ انْصَرَفُوا فَكَانَ لِلنَّبِىّ ﷺ رَكعَتَان، وَلِكُل وَاحدٍ منَ الفَريضَةِ رَكْعَةٌ".  

"عَنْ زَيْد بن ثَابِت أَنَّهُ سُئِلَ عَنْ صَلَاةِ الْخَوْفِ فَقَالَ: قامَ رَسولُ الله ﷺ ، فَصَلَّى بِهِم، فَقَامَ صَفٌ خَلْفَهُ، وَصَفٌّ مُوَازِى الْعَدُوِّ، فَصَلَّى بِهِم رَكْعَة، ثمَّ ذَهَبَ هَؤُلَاءِ إِلَى مَصَافِّ هَؤُلَاءِ، وَجَاءَ هَؤُلَاءِ فَصَلَّى بِهم رَكْعَةً، ثُمَّ انْصَرَفَ".  

"عَنِ ابْن مَسْعُودٍ قَالَ: كُنَّا معَ رَسُولِ الله ﷺ فَصَفَّ صَفّا خَلْفَهُ، وَصَفّا مُوَازىَ الْعَدُوِّ، وَهُمْ في صَلَاةٍ كُلُّهُمْ، فَكَبَّرَ وَكَبَّرُوا جَميعًا، فَصَلَّى بالصَّفِّ الَّذى

يَلِيهِ رَكْعَةً، ثُمَّ ذَهَبَ هَؤَلَاءِ، وَجَاءَ هَؤُلَاءِ فَصَلَّى بِهِمْ رَكعَةً، ثُمَّ قَامَ هو وَالَّذِى صَلَّى بِهِمْ الرَّكْعَةَ الثَّانيَةَ فَصَفُّوا مَكَانَهُمْ، ثُمَّ ذَهَبَ هَؤُلَاء إِلَى مَصَافِّ هَؤُلَاءِ، وَجَاءَ أُولَئِكَ فَقَضَوْا رَكْعَةً".
