Sunan an-Nasa'i 1537

Qutaybah narrated to us, from Malik, from Yazid ibn Ruman, from Salih ibn Khawwat, from someone who prayed the fear prayer with the Messenger of Allah (peace and blessings be upon him) on the day of Dhat al-Riqa‘: One group formed a row with him, while another group faced the enemy. He led those with him in one rak‘ah, then remained standing while they completed the prayer on their own. They then moved away and formed a row facing the enemy. The other group came, and he led them in the remaining rak‘ah of his prayer. Then he remained seated while they completed the prayer on their own, and he said the taslim with them.
