English translation
942. Narrated Shu'aib: I asked Az-Zuhri, “Did the Prophet ﷺ ever offer the Salāt-ul-Khauf (Fear prayer)?” Az-Zuhri said, “I was told by Sālim that ‘Abdullāh bin ‘Umar رضي الله عنهم had said, ‘I took part in a holy battle with Allāh’s Messenger ﷺ in Najd. We faced the enemy and arranged ourselves in rows. Then Allāh’s Messenger ﷺ stood up to lead the Salāt (prayer) and one party stood to offer Salāt (prayer) with him while the other faced the enemy. Allāh’s Messenger ﷺ and the former party bowed and performed two prostrations. Then that party left (after completing their 2nd Rak'a individually with Taslim, while the Prophet ﷺ kept on standing). Then they took the place of those who had not offered Salât (prayer). [The second (latter) party] joined Allâh's Messenger ﷺ who prayed one Rak'a (i.e. his 2nd Rak'a with the latter party) and performed two prostrations and finished his Salât (prayer) with Taslim. Then everyone of them [of the 2nd (latter) party] bowed once and performed two prostrations individually (i.e. completed their 2nd Rak'a and finished their Salât (prayer) with Taslim)."
