Mishkat al-Masabih #1345

He said: God’s Messenger led us in the prayer in time of danger and we drew up in two rows behind him with the enemy between us and the qibla. The Prophet said, "God is most great” and we all said it; then he bowed and we all bowed; then he raised his head after bowing and we all raised ours; then he and the row next him went down in prostration while the rear row stood facing the enemy; then when the Prophet finished the prostration and the row next him stood up, the rear row went down in prostration; then they stood up; then the rear row went to the front and the front row to the rear; then the Prophet bowed and we all bowed; then he raised his head after bowing and we all raised ours; then he and the row next him which had been in the rear in the first rak'a went down in prostration while the rear row stood facing the enemy; then when the Prophet and the row next him finished the prostration the rear row went down and prostrated them selves; then the Prophet, uttered the salutation and we all did so. Muslim transmitted it.
