Jarir bin 'Abdullah (May Allah be pleased with him) said:
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].

وعن جرير رضي الله عنه قال: سألت رسول الله ﷺ عن نظر الفجأة فقال:
"اصرف بصرك" ((رواه مسلم)).
