وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، عَنْ سُفْيَانَ، عَنْ مُوسَى بْنِ، عُقْبَةَ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم صَلاَةَ الْخَوْفِ فِي بَعْضِ أَيَّامِهِ فَقَامَتْ طَائِفَةٌ مَعَهُ وَطَائِفَةٌ بِإِزَاءِ الْعَدُوِّ فَصَلَّى بِالَّذِينَ مَعَهُ رَكْعَةً ثُمَّ ذَهَبُوا وَجَاءَ الآخَرُونَ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ قَضَتِ الطَّائِفَتَانِ رَكْعَةً رَكْعَةً - قَالَ - وَقَالَ ابْنُ عُمَرَ فَإِذَا كَانَ خَوْفٌ أَكْثَرَ مِنْ ذَلِكَ فَصَلِّ رَاكِبًا أَوْ قَائِمًا تُومِئُ إِيمَاءً .
Ibn Umar reported that the Messenger of Allah (ﷺ) observed prayer in danger on some day (in this way):a group stood with him (the Holy Prophet) (for prayer) and the other group stood In front of the enemy. Then those who were with (him) observed one rak'ah of prayer and they went back and the others came and they observed one rak'ah (with him). Then both the groups completed one rak'ah each. Ibn Umar said: When there is greater danger, then observe prayer even on the ride or with the help of gestures in a standing posture
