Yazid bin Ruman reported,

Salih bin Khawat reported, from someone who prayed the fear prayer with the Messenger of Allah ﷺ on the day of Dhat al-Riqa, that one group formed a row with him while another group faced the enemy. He led the group that was with him in one rakat, then remained standing while they completed the prayer for themselves. They then withdrew and formed a row facing the enemy, and the other group came forward. He led them in the rakat that remained of his prayer, then remained seated while they completed the prayer for themselves, and then he said the closing salutation with them.

حدثني يحيى عن مالك

عن يزيد بن رومان

عن صالح بن خوات عمن صلى مع رسول الله ﷺ يوم ذات الرقاع صلاة الخوف أن طائفة صفت معه وصفت طائفة وجاه العدو فصلى بالتي معه ركعة ثم ثبت قائما وأتموا لأنفسهم ثم انصرفوا فصفوا وجاه العدو وجاءت الطائفة الأخرى فصلى بهم الركعة التي بقيت من صلاته ثم ثبت جالسا وأتموا لأنفسهم ثم سلم بهم
