837. It was narrated from Abu Bakr that the Prophet ﷺ offered the fear prayer (Salat Al-Khauf). He led those who were behind him in two Rak'ah and those who came (after them) in two Rak'ah, so the Prophet ﷺ prayed four Rak'ahs and each group prayed two. (Using translation from Nasāʾī 836)
عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى صَلَاةَ الْخَوْفِ فَصَلَّى بِالَّذِينَ خَلْفَهُ رَكْعَتَيْنِ وَبِالَّذِينَ جَاءُوا رَكْعَتَيْنِ فَكَانَتْ لِلنَّبِيِّ ﷺ أَرْبَعًا وَلَهُمْ وَلِهَؤُلَاءِ رَكْعَتَيْنِ رَكْعَتَيْنِ
