Thalaba bin Zahdam reported,

We were with Saeed bin al-As in Tabaristan when he asked, "Which of you prayed the prayer of fear with the Messenger of Allah ﷺ?"Hudhayfah replied, "I did."So he led one group in one rakah and the other group in one rakah, and they did not make up the missed rakah.

كنا مع سعيد بن العاص بطبرستان فقال: أيكم صلى مع رسول الله ﷺ صلاة الخوف؟ فقال حذيفة: أنا فصلى بهؤلاء ركعة، وبهؤلاء ركعة، ولم يقضوا.
