Riyad as-Salihin 1625
The Book of the Prohibited actions
Prohibition of gazing at women and Beardless Handsome Boys except in Exigency
وَعَنْ جرير رَضِيَ اللَّه عَنْهُ قَالَ: سَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ عَنْ نَظَرِ الْفَجْأَةِ فَقَالَ: اصْرِفْ بَصَرَكَ ((رَوَاهُ مُسْلِم)).
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].
