Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن جرير رضي الله عنه قال: سألت رسول الله صلى الله عليه وسلم عن نظر الفجأة فقال: "اصرف بصرك" ((رواه مسلم)).
I asked the Messenger of Allah (ﷺ) about (the Islamic ruling on) accidental glance (i.e., at a woman one is not Islamically allowed to look at) and he ordered me to turn my eyes away.[Muslim].
