Narrated Sahl ibn al-Hanzaliyyah: The iqamah for the morning prayer was pronounced and the Messenger of Allah ﷺ began to offer prayer while he was looking at the mountain-pass. (Abu Dawud elaborated that the Prophet had sent a horseman to the mountain-pass at night in order to keep watch. )

916. Commentary:
This hadith, and other ahadith in which turning (during prayer) is prohibited, are reconciled in this way: that looking (to the side) without turning the neck is permissible in cases of extreme necessity; otherwise, it is prohibited.
