Narrated Salih bin Khawwat: Concerning those who witnessed the Fear Prayer that was performed in the battle of Dhat-ur-Riqa' in the company of Allah's Apostle; One batch lined up behind him while another batch (lined up) facing the enemy. The Prophet led the batch that was with him in one rak`a, and he stayed in the standing posture while that batch completed their (two rak`at) prayer by themselves and went away, lining in the face of the enemy, while the other batch came and he (i.e. the Prophet) offered his remaining rak`a with them, and then, kept on sitting till they completed their prayer by themselves, and he then finished his prayer with Taslim along with them.

Narrated Sahl bin Abi Hathma: (describing the Fear prayer): The Imam stands up facing the Qibla and one batch of them (i.e. the army) (out of the two) prays along with him and the other batch faces the enemy. The Imam offers one rak`a with the first batch they themselves stand up alone and offer one bowing and two prostrations while they are still in their place, and then go away to relieve the second batch, and the second batch comes (and takes the place of the first batch in the prayer behind the Imam) and he offers the second rak`a with them. So he completes his two-rak`at and then the second batch bows and prostrates two prostrations (i.e. complete their second rak`a and thus all complete their prayer).
