Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ آدَمَ حَدَّثَنَا سُفْيَانُ عَنْ مُوسَى بْنِ عُقْبَةَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَاةَ الْخَوْفِ فِي بَعْضِ أَيَّامِهِ فَقَامَتْ طَائِفَةٌ مَعَهُ وَطَائِفَةٌ بِإِزَاءِ الْعَدُوِّ فَصَلَّى بِالَّذِينَ مَعَهُ رَكْعَةً ثُمَّ ذَهَبُوا وَجَاءَ الْآخَرُونَ فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ قَضَتْ الطَّائِفَتَانِ رَكْعَةً رَكْعَةً.
English Translation
Yahya ibn Adam narrated to us: Sufyan narrated from Musa ibn Uqbah from Nafi from Ibn Umar who said: The Messenger of Allah (peace be upon him) prayed the prayer of fear on one of his expeditions. One group stood with him and another faced the enemy. He prayed one rak'ah with those who were with him, then they went and the others came. He prayed one rak'ah with them, then both groups made up one rak'ah each.
