Prohibition of gazing at women and Beardless Handsome Boys except in Exigency

Abu Sa'id Al-Khudri (May Allah be pleased with him) said:
The Prophet ﷺ said, "Avoid sitting on roadsides." His Companions said: "O Messenger of Allah ﷺ, there is no other alternative but to sit there to talk." Thereupon the Messenger of Allah ﷺ said, "If you have to sit at all, then fulfill the rights of the road." They asked: "What are their rights?" Thereupon he said, "Lowering the gaze (so that you may not stare at unlawful things), refraining from doing some harm to others, responding to greeting (i.e., saying 'Wa'alaikumus- salam' to one another) and commanding the good and forbidding the evil."

[Al-Bukhari and Muslim].

وعن أبي سعيد الخُدري رضي الله عنه عن النبي ﷺ قال: "إياكم والجلوس في الطرقات". قالوا: يا رسول الله ما لنا من مجالسنا بُد نتحدث فيها. فقال رسول الله ﷺ : "فإذا أبيتم إلا المجلس، فأعطوا الطريق حقه" قالوا: وما حق الطريق يا رسول الله؟ قال: "غض البصر، وكف الأذى، ورد السلام، والأمر المعروف والنهي عن المنكر" ((متفق عليه)).

Abu Talhah Zaid bin Sahl (May Allah be pleased with him) said:
We were sitting and talking on a platform in front of our house when the Messenger of Allah ﷺ stopped by us and said, "Why do you sit on roads? Avoid sitting in them." We replied: "We sit there intending no harm. We only sit and discuss (religious) knowledge and talk." He said, "If you have to sit, you should fulfill the rights of the road: Lower your gaze, respond to greetings and talk in a good manner."

[Muslim].

وعن أبي طلحة زيد بن سهل رضي الله عنه قال: كنا قعودًا بالأفنية نتحدث فيها فجاء رسول الله ﷺ فقالم علينا فقال: "ما لكم ولمجالس الصعدات؟ فقلنا: إنما قعدنا لغير ما بأس، قعدنا نتذاكر، ونتحدث. قال: "إما لا فأدوا حقها: غض البصر، ورد السلام، وحسن الكلام" ((رواه مسلم)). "الصُّعُدات" بضم الصاد والعين، أي: الطرقات.

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)).

Umm Salamah (May Allah be pleased with her) said:
I was with the Messenger of Allah ﷺ along with Maimunah (May Allah be pleased with her) when Ibn Umm Maktum (May Allah be pleased with him) (who was blind) came to visit him. (This incident took place after the order of Hijab). The Prophet ﷺ told us to hide ourselves from him (i.e., observe Hijab). We said: "O Messenger of Allah ﷺ, he is blind and is unable to see us, nor does he know us." He replied; "Are you also blind and unable to see him?"

[Abu Dawud and At- Tirmidhi].

وعن أم سلمة رضي الله عنها قالت: كنت عند رسول الله ﷺ وعنده ميمونة، فأقبل ابن أم مكتوم، وذلك بعد أن أُمرنا بالحجاب فقال النبي ﷺ : "احتجبا منه" فقلنا: يا رسول الله إلىس هو أعمى لا يبصرنا، ولا يعرفنا؟ فقال النبي ﷺ : "أفعمياوان أنتما ألستما تبصرانه؟!" ((رواه أبو داود والترمذي: وقال حديث حسن صحيح)).

Abu Sa'id Al-Khudri (May Allah be pleased with him) said:
The Messenger of Allah ﷺ said, "A man must not look at a man's private parts nor must a woman look at a woman's private parts; neither should two men lie naked under one cover, nor should two women lie naked under the same cover."

[Muslim].

وعن أبي سعيد رضي الله عنه أن رسول الله ﷺ قال: "لا ينظر الرجل إلى عورة الرجل، ولا المرأة إلى عورة المرأة، ولا يفضي الرجل إلى الرجل في ثوب واحد، ولا تفضي المرأة إلى المرأة في ثوب واحد" ((رواه مسلم)).
