"Abdullah bin 'Umar used to narrate that he offered the fear prayer with the Messenger of Allah ﷺ. He said: 'The Prophet ﷺ said the takbir and one group of us formed a row behind him while the other group faced the enemy. The Prophet ﷺ led them in bowing once and prostrating twice, then they moved away and faced the enemy, and the other group came and prayed with the Prophet ﷺ, doing likewise. Then he said the taslim, then each man of both groups stood and prayed by himself, bowing once and prostrating twice.'"  

أَنَّهُ صَلَّى صَلاَةَ الْخَوْفِ مَعَ رَسُولِ اللَّهِ ﷺ قَالَ كَبَّرَ النَّبِيُّ ﷺ وَصَفَّ خَلْفَهُ طَائِفَةٌ مِنَّا وَأَقْبَلَتْ طَائِفَةٌ عَلَى الْعَدُوِّ فَرَكَعَ بِهِمُ النَّبِيُّ ﷺ رَكْعَةً وَسَجْدَتَيْنِ ثُمَّ انْصَرَفُوا وَأَقْبَلُوا عَلَى الْعَدُوِّ وَجَاءَتِ الطَّائِفَةُ الأُخْرَى فَصَلُّوا مَعَ النَّبِيِّ ﷺ فَفَعَلَ مِثْلَ ذَلِكَ ثُمَّ سَلَّمَ ثُمَّ قَامَ كُلُّ رَجُلٍ مِنَ الطَّائِفَتَيْنِ فَصَلَّى لِنَفْسِهِ رَكْعَةً وَسَجْدَتَيْنِ

أَنَّهُ صَلَّاهَا مَعَ النَّبِيِّ ﷺ قَالَ فَكَبَّرَ رَسُولُ اللهِ ﷺ فَصَفَّ وَرَاءَهُ طَائِفَةٌ مِنَّا وَأَقْبَلَتْ طَائِفَةٌ عَلَى الْعَدُوِّ فَرَكَعَ بِهِمْ رَسُولُ اللهِ ﷺ رَكْعَةً وَسَجْدَتَيْنِ سَجَدَ مِثْلَ نِصْفِ صَلَاةِ الصُّبْحِ ثُمَّ انْصَرَفُوا فَأَقْبَلُوا عَلَى الْعَدُوِّ فَجَاءَتِ الطَّائِفَةُ الْأُخْرَى فَصَفُّوا مَعَ النَّبِيِّ ﷺ فَفَعَلَ مِثْلَ ذَلِكَ ثُمَّ سَلَّمَ النَّبِيُّ ﷺ فَقَامَ كُلُّ رَجُلٍ مِنَ الطَّائِفَتَيْنِ فَصَلَّى لِنَفْسِهِ رَكْعَةً وَسَجْدَتَيْنِ  

[Machine] I prayed the prayer of fear behind the Prophet ﷺ. A group of us lined up behind him, while another group went towards the enemy. They shouted the takbeer (saying "Allahu Akbar") and then he (the Prophet) led them in rukoo' (bowing) and sujood (prostration) twice. Then the group that was with him departed, and they (the other group) went towards the enemy. Then another group came and lined up behind him, and the Prophet ﷺ made the tasleem (saying "Assalamu Alaikum" to end the prayer). Then every man from both groups performed a two-rakah prayer for himself.  

«صَلَّيْتُ مَعَ نَبِيِّ اللهِ ﷺ صَلَاةَ الْخَوْفِ فَصَفَّ وَرَاءَهُ طَائِفَةً مِنَّا وَأَقْبَلَتْ طَائِفَةٌ عَلَى الْعَدُوِّ فَكَبَّرَ ثُمَّ رَكَعَ بِهِمْ وَسَجَدَ سَجْدَتَيْنِ ثُمَّ انْصَرَفَتِ الطَّائِفَةُ الَّتِي مَعَهُ فَأَقْبَلُوا عَلَى الْعَدُوِّ وَجَاءَتِ الطَّائِفَةُ الْأُخْرَى فَصُفُّوا وَرَاءَهُ ثُمَّ سَلَّمَ نَبِيُّ اللهِ ﷺ فَقَامَ كُلُّ رَجُلٍ مِنَ الطَّائِفَتَيْنِ فَقَضَى لِنَفْسِهِ رَكْعَةً وَسَجْدَتَيْنِ»

"The Messenger of Allah ﷺ offered the fear prayer. He stood and said the takbir, and a group of us prayed behind him while another group was facing the enemy. The Messenger of Allah ﷺ bowed once and prostrated twice with them, then they moved away but did not say the taslim. They went to face the enemy and lined up in their places, and the other group came and formed a row behind the Messenger of Allah ﷺ, and he led them in praying, bowing once and prostrating twice. Then the Messenger of Allah ﷺ said the taslim and he had bowed twice and prostrated four times. Then the two groups stood up and each man prayed by himself, bowing once and prostrating twice." Abu Bakr IB As-Sunni said: "Az-Zuhri heard two hadiths from Ibn 'Umar, and he did not hear this from him." (Using translation from Nasāʾī 1541)   

«صَلَّى رَسُولُ اللهِ ﷺ صَلَاةَ الْخَوْفِ قَامَ فَكَبَّرَ فَصَلَّى خَلْفَهُ طَائِفَةٌ مِنَّا وَطَائِفَةٌ مُوَاجِهَةَ الْعَدُوِّ فَرَكَعَ بِهِمْ رَسُولُ اللهِ ﷺ رَكْعَةً وَسَجَدَ سَجْدَتَيْنِ ثُمَّ انْصَرَفُوا وَلَمْ يُسَلِّمُوا وَأَقْبَلُوا عَلَى الْعَدُوِّ فَصَفُّوا مَكَانَهُمْ وَجَاءَتِ الطَّائِفَةُ الْأُخْرَى فَصَلَّوْا خَلْفَ رَسُولِ اللهِ ﷺ فَصَلَّى بِهِمْ رَكْعَةً وَسَجْدَتَيْنِ ثُمَّ سَلَّمَ رَسُولُ اللهِ ﷺ وَقَدْ أَتَمَّ رَكْعَتَيْنِ وَأَرْبَعَ سَجَدَاتٍ ثُمَّ قَامَتِ الطَّائِفَتَانِ فَصَلَّى كُلُّ إِنْسَانٍ مِنْهُمْ لِنَفْسِهِ رَكْعَةً وَسَجْدَتَيْنِ»  

" عَنِ ابْنِ عُمَرَ أَنَّهُ صَلَّى مَعَ رَسُولِ الله ﷺ صَلاَةَ الْخَوْفِ قَالَ: فَكَبَّرَ رَسُولُ الله ﷺ فَصَفَّ وَرَاءهُ طَائِفَةً مِنَّا، وَأَقْبَلَتْ طائِفَةٌ عَلَى الْعَدُوِّ، فَرَكَعَ لَهُمُ النَّبِى ﷺ رَكعَةً وَسَجْدَتيْنِ، يَسْجُدُ مِثْلَ نِصْفِ صَلاَةِ الصُّبْح، ثُمَّ انْصَرَفُوا فَأَقْبَلُوا عَلَى الْعَدُوِّ، وَجَاءَت الطَّائفَةُ الأُخْرى فَصَفُّوا مَعَ النَّبِىِّ ﷺ فَفَعَلَ مِثل ذَلِكَ، ثُمَّ سَلَّمَ، فَقَامَ كُلُّ رَجُلٍ مِنَ الطَّائِفَتَينَ فَصَلَّى لِنَفْسِهِ رَكعَةً وَسَجْدَتيْنِ ".
