The Imam al-Bukhari (may Allah have mercy on him) said in his Sahih: Chapter on the Prayer of Fear: Abu al-Yaman narrated to us, Shu'ayb informed us, from al-Zuhri, who said:

The reciter: In the name of Allah, the Most Merciful, the Bestower of Mercy. And all praise is due to Allah, Lord of the worlds. And may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. As for what follows:

Chapter on the Prayer of Fear:
Abu al-Yaman narrated to us, Shu'ayb informed us, from al-Zuhri, who said: I asked him whether the Prophet (peace and blessings be upon him) prayed the Prayer of Fear? He said: Salim informed me that 'Abdullah ibn 'Umar (may Allah be pleased with them both) said: .

The Shaykh : This is clear that it is close to the context of the noble verse, that the Messenger of Allah (peace and blessings be upon him) prayed with a group with him for one rak'ah, and when he stood up, they completed it for themselves. The apparent context that is with us is that they did not complete it for themselves, because he said the place of the group that had not prayed. But in the hadith of Salih ibn Khatam, they completed it for themselves, then they went and stood facing the enemy. Then the first group came and entered with the Prophet (peace and blessings be upon him) in the second rak'ah, and he prayed the rak'ah with them. Then he sat for the tashahhud, and they stood up by themselves and made up what was due on them before the Prophet (peace and blessings be upon him) said the salam. Then he said the salam with them. Perhaps you should look at al-Fath regarding his statement: "and he prostrated twice, then they moved away."
