“Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah performed Salah (prayer) with his followers during the armed expedition at Dhat al-Riqa‘ in a fearful condition. The Messenger of Allah divided his companions in two groups. One group was made to stand up facing the enemy and the other group behind him for Salah (prayer). He said Takbir (Allah is great beyond description) and they also did so. He recited and they remained silent. He performed Ruku‘ (bowing down on one’s knees) and they also did so. He performed Sajdah (prostration), and they also did so. The Messenger of Allah in order to complete remained standing but they performed one Rak‘at for themselves, then they said Salam (the phrase of offering greeting of peace) to each other. They then went to stand guard in place of the group facing the enemy. This group stood behind the Messenger of Allah who performed one Rak‘at with them, then said Tashahhud (testimonies of belief) and Salam (the phrase of offering greeting of peace) to them. They then stood up to perform one Rak‘at for themselves, then said Salam (the phrase of offering greeting of peace) to each other.’”
