Sunan Ibn Majah Book 5, Hadith 1260

حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، حَدَّثَنَا عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ صَلَّى بِأَصْحَابِهِ صَلاَةَ الْخَوْفِ فَرَكَعَ بِهِمْ جَمِيعًا ثُمَّ سَجَدَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَالصَّفُّ الَّذِينَ يَلُونَهُ وَالآخَرُونَ قِيَامٌ حَتَّى إِذَا نَهَضَ سَجَدَ أُولَئِكَ بِأَنْفُسِهِمْ سَجْدَتَيْنِ ثُمَّ تَأَخَّرَ الصَّفُّ الْمُقَدَّمُ حَتَّى قَامُوا مُقَامَ أُولَئِكَ وَتَخَلَّلَ أُولَئِكَ حَتَّى قَامُوا مُقَامَ الصَّفِّ الْمُقَدَّمِ فَرَكَعَ بِهِمُ النَّبِيُّ ـ صلى الله عليه وسلم ـ جَمِيعًا ثُمَّ سَجَدَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَالصَّفُّ الَّذِي يَلُونَهُ فَلَمَّا رَفَعُوا رُءُوسَهُمْ سَجَدَ أُولَئِكَ سَجْدَتَيْنِ فَكُلُّهُمْ قَدْ رَكَعَ مَعَ النَّبِيِّ ـ صلى الله عليه وسلم ـ وَسَجَدَتْ طَائِفَةٌ بِأَنْفُسِهِمْ سَجْدَتَيْنِ وَكَانَ الْعَدُوُّ مِمَّا يَلِي الْقِبْلَةَ ‏.‏

It was narrated from Jabir bin ‘Abdullah that the Prophet (ﷺ) led his Companions in the fear prayer. He led them all in bowing, then the Messenger of Allah (ﷺ) and the row nearest him prostrated, and the others stood up, then when he stood up, they prostrated twice by themselves. Then the front row moved back and took their place, and they moved forward until they formed the front row. Then the Prophet (ﷺ) led them all in bowing, then the Messenger of Allah (ﷺ) and the row nearest to him prostrated, and when they raised their heads, the others prostrated twice. So all of them bowed with the Prophet (ﷺ) and some of them prostrated by themselves, and the enemy was in the direction of the Qiblah
