“The Messenger of Allah ﷺ said concerning the fear prayer: “The Imam should lead one group in prayer, and they should perform one prostration, and there should be another group between them and the enemy (guarding them). Then those who did the prostration with their leader should move away, and take the place of those who have not yet prayed. Then those who have not yet prayed should come forward and perform one prostration with their leader. Then their leader should move away, and his prayer will be complete. Then each group should perform one prostration by itself. If the fear is too great, then (they should pray) on foot or riding.’” He said: What is meant by prostration here is a Rak’ah.  

قَالَ رَسُولُ اللَّهِ ﷺ فِي صَلاَةِ الْخَوْفِ أَنْ يَكُونَ الإِمَامُ يُصَلِّي بِطَائِفَةٍ مَعَهُ فَيَسْجُدُونَ سَجْدَةً وَاحِدَةً وَتَكُونُ طَائِفَةٌ مِنْهُمْ بَيْنَهُمْ وَبَيْنَ الْعَدُوِّ ثُمَّ يَنْصَرِفُ الَّذِينَ سَجَدُوا السَّجْدَةَ مَعَ أَمِيرِهِمْ ثُمَّ يَكُونُونَ مَكَانَ الَّذِينَ لَمْ يُصَلُّوا وَيَتَقَدَّمُ الَّذِينَ لَمْ يُصَلُّوا فَيُصَلُّوا مَعَ أَمِيرِهِمْ سَجْدَةً وَاحِدَةً ثُمَّ يَنْصَرِفُ أَمِيرُهُمْ وَقَدْ صَلَّى صَلاَتَهُ وَيُصَلِّي كُلُّ وَاحِدَةٍ مِنَ الطَّائِفَتَيْنِ بِصَلاَتِهِ سَجْدَةً لِنَفْسِهِ فَإِنْ كَانَ خَوْفٌ أَشَدَّ مِنْ ذَلِكَ فَرِجَالاً أَوْ رُكْبَانًا قَالَ يَعْنِي بِالسَّجْدَةِ الرَّكْعَةَ  

Yahya related to me from Malik from Nafi that Abdullah ibn Umar, when asked about the fear prayer said, "The imam and a group of people go forward and the imam prays a raka with them, while another group, who have not yet prayed, position themselves between him and the enemy. When those who are with him have prayed a raka they draw back to where those who have not prayed are, and do not say the taslim. Then those who have not prayed come forward and pray a raka with him. Then the imam leaves, as he has now prayed two rakas. Everyone else in the two groups stands and prays a raka by himself after the imam has left. In this way each of the two groups will have prayed two rakas. If the fear is greater than that, then the men pray standing on their feet or mounted, either facing the qibla or otherwise."  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ إِذَا سُئِلَ عَنْ صَلاَةِ الْخَوْفِ قَالَ يَتَقَدَّمُ الإِمَامُ وَطَائِفَةٌ مِنَ النَّاسِ فَيُصَلِّي بِهِمُ الإِمَامُ رَكْعَةً وَتَكُونُ طَائِفَةٌ مِنْهُمْ بَيْنَهُ وَبَيْنَ الْعَدُوِّ لَمْ يُصَلُّوا فَإِذَا صَلَّى الَّذِينَ مَعَهُ رَكْعَةً اسْتَأْخَرُوا مَكَانَ الَّذِينَ لَمْ يُصَلُّوا وَلاَ يُسَلِّمُونَ وَيَتَقَدَّمُ الَّذِينَ لَمْ يُصَلُّوا فَيُصَلُّونَ مَعَهُ رَكْعَةً ثُمَّ يَنْصَرِفُ الإِمَامُ وَقَدْ صَلَّى رَكْعَتَيْنِ فَتَقُومُ كُلُّ وَاحِدَةٍ مِنَ الطَّائِفَتَيْنِ فَيُصَلُّونَ لأَنْفُسِهِمْ رَكْعَةً رَكْعَةً بَعْدَ أَنْ يَنْصَرِفَ الإِمَامُ فَيَكُونُ كُلُّ وَاحِدَةٍ مِنَ الطَّائِفَتَيْنِ قَدْ صَلَّوْا رَكْعَتَيْنِ فَإِنْ كَانَ خَوْفًا هُوَ أَشَدَّ مِنْ ذَلِكَ صَلَّوْا رِجَالاً قِيَامًا عَلَى أَقْدَامِهِمْ أَوْ رُكْبَانًا مُسْتَقْبِلِي الْقِبْلَةِ أَوْ غَيْرَ مُسْتَقْبِلِيهَا  

[Machine] The Messenger of Allah ﷺ said:

"In the prayer of fear, the Imam stands and a group of people stand with him. They all prostrate in one prostration. Another group stays between them and the enemy. Then those who have prostrated with the Imam leave and take the place of those who have not prayed. Those newcomers pray with their Imam in one prostration. Then their Imam leaves and each person from the two groups prays with their own prayer, one prostration. If the fear is more severe than that, then men or riders should do the same."  

قَالَ رَسُولُ اللَّهِ ﷺ «فِي صَلَاةِ الْخَوْفِ يَقُومُ الْإِمَامِ وَطَائِفَةٌ مِنَ النَّاسِ مَعَهُ فَيَسْجُدُونَ سَجْدَةً وَاحِدَةً وَتَكُونُ طَائِفَةٌ بَيْنَهُمْ وَبَيْنَ الْعَدُوِّ ثُمَّ يَنْصَرِفُ الَّذِينَ سَجَدُوا سَجْدَةً مَعَ الْإِمَامِ وَيَكُونَونَ مَكَانَ الَّذِينَ لَمْ يُصَلُّوا وَيَجِيءُ أُولَئِكَ فَيُصَلُّونَ مَعَ إِمَامِهِمْ سَجْدَةً وَاحِدَةً ثُمَّ يَنْصَرِفُ إِمَامُهُمْ فَيُصَلِّي كُلُّ وَاحِدٍ مِنَ الطَّائِفَتَيْنِ بِصَلَاتِهِ سَجْدَةً وَاحِدَةً فَإِنْ كَانَ خَوْفًا أَشَدَّ مِنْ ذَلِكَ فَرِجَالًا أَوْ رُكْبَانًا»  

«صَلاةُ الْخَوْفِ قِيَامُ الإِمَام وَطَائِفَةٌ منَ النَّاسِ مَعَهُ، فَيَسْجُدُونَ سَجْدَةً وَاحدَةً، وَيكُونُ طَائفَةٌ بَينَهُمْ وَبَينَ الْعَدُوِّ، ثُمَّ يَنْصَرِفُ الَّذينَ سَجَدُوا مَعَ أَميرهِمْ فَيكُونُونَ مَكَانَ الَّذين لَمْ يُصَلُّوا، فَيُصَلُّونَ مَعَ أَمِيرِهِمْ سَجْدَةً وَاحدَةً، ثُمَّ يَنْصَرِفُ أَمِيرُهُمْ قَدْ قَضَى صَلاتَهُ، وَيُصَلِّى كُلُّ وَاحِدٍ مِنَ الطَّائِفَتَين بِصَلاتِه سَجْدَةً لِنَفْسِهِ، فَإِنْ كانَ خَوْفٌ أشَدُّ مِنْ ذَلِكَ فَرِجالًا وَرُكْبَانًا»
