Concerning those who witnessed the Fear Prayer that was performed in the battle of Dhât-ur-Riqâ in the company of Allâh's Messenger (ﷺ); one batch lined up behind him while another batch (lined up) facing the enemy. The Prophet (ﷺ) 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 (ﷺ) 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. [5:451-O.B]
