Sunan Abi Dawud 1238
Narrated Salih b. Khawwat:
On the authority of a person who offered the prayer in time of danger along with the Messenger of Allah (ﷺ) at the battle of Dhat al-Riqa. One section of people stood in the row of prayer along with the Messenger of Allah (ﷺ) and the other section remained standing in front of the enemy. He led those who were with him in one rak'ah and remained standing (in his place) and they completed (the second rak'ah) by themselves. Then they turned away and arrayed before the enemy. Thereafter the other section came and he led them in the rak'ah which remained from his prayer. He then remained sitting (in his place) and they completed their one rak'ah by themselves. He then uttered the salutation along with them.
حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ يَزِيدَ بْنِ رُومَانَ، عَنْ صَالِحِ بْنِ خَوَّاتٍ، عَمَّنْ صَلَّى مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ ذَاتِ الرِّقَاعِ صَلاَةَ الْخَوْفِ أَنَّ طَائِفَةً صَفَّتْ مَعَهُ وَطَائِفَةً وِجَاهَ الْعَدُوِّ فَصَلَّى بِالَّتِي مَعَهُ رَكْعَةً ثُمَّ ثَبَتَ قَائِمًا وَأَتَمُّوا لأَنْفُسِهِمْ ثُمَّ انْصَرَفُوا وَصَفُّوا وِجَاهَ الْعَدُوِّ وَجَاءَتِ الطَّائِفَةُ الأُخْرَى فَصَلَّى بِهِمُ الرَّكْعَةَ الَّتِي بَقِيَتْ مِنْ صَلاَتِهِ ثُمَّ ثَبَتَ جَالِسًا وَأَتَمُّوا لأَنْفُسِهِمْ ثُمَّ سَلَّمَ بِهِمْ ‏.‏ قَالَ مَالِكٌ وَحَدِيثُ يَزِيدَ بْنِ رُومَانَ أَحَبُّ مَا سَمِعْتُ إِلَىَّ ‏.‏
