Sunan an-Nasa'i 1550

‘Amr ibn ‘Ali narrated to us; he said: ‘Abd al-‘Aziz ibn ‘Abd al-Samad narrated to us; he said: Mansur narrated to us, from Mujahid, from Abu ‘Ayyash al-Zuraqi, who said: We were with the Messenger of Allah (peace and blessings be upon him) at ‘Usfan, where he led us in the noon prayer. Khalid ibn al-Walid was leading the polytheists that day. The polytheists said, “We caught them off guard; they were unaware.” Then the fear prayer was revealed—that is, the fear prayer was prescribed—between the noon and afternoon prayers. The Messenger of Allah (peace and blessings be upon him) led us in the afternoon prayer and divided us into two groups: one group prayed with the Prophet (peace and blessings be upon him), and one group guarded him. He proclaimed Allah’s greatness with those nearest to him and those guarding them. Then he bowed, and both groups bowed with him. Then those nearest to him prostrated. They moved back, and the others moved forward and prostrated. Then he stood and led them all in the second rak‘ah, both those nearest to him and those guarding him. He prostrated with those nearest to him. Then they moved back and took the positions of their companions, and the others moved forward and prostrated. Then he said the taslim. Each group had prayed two rak‘ahs with their imam. He also prayed the fear prayer once in the land of Banu Sulaym.
