(290) Chapter: Prohibition of gazing at women and Beardless Handsome Boys except in Exigency

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].

Commentary: If one suddenly sees a woman who is not a Mahram, he must at once turn away his glance from her. One should not gaze at her because then his intention is also included in his look which is a sin and constitutes the fornication of the eye. Some religious scholars have also forbidden looking at beardless handsome boys in the same way as is the case with women whom one is not allowed to see.
