It was narrated that Ibn 'Abbas said:

The Messenger of Allah (ﷺ) offered the fear prayer in Dhu Qarad - land belonging to Banu Sulaim. The people formed two rows behind him: one row facing the enemy and one row behind him. He led the row that was behind him in praying one rak'ah, then they moved back to where the others were and the others took their places, then he led them in praying another rak'ah.
