Abu Sa’id al-Khudri reported: The Messenger of Allah, peace and blessings be upon him, said, “A man should not look at the nakedness of another man, and a woman should not look at the nakedness of another woman. A man should not lie with another man under a single blanket, and a woman should not lie with another woman under a single blanket.”

Al-Nawawi said, “Likewise it is forbidden for a man to look at a beardless youth if he has a handsome appearance, whether he looks with passion or not, whether he is safe from temptation or he fears it. This is the correct and preferred opinion of credible scholars, as transmitted from Al-Shafi’i.”

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَنْظُرُ الرَّجُلُ إِلَى عَوْرَةِ الرَّجُلِ وَلَا الْمَرْأَةُ إِلَى عَوْرَةِ الْمَرْأَةِ وَلَا يُفْضِي الرَّجُلُ إِلَى الرَّجُلِ فِي ثَوْبٍ وَاحِدٍ وَلَا تُفْضِي الْمَرْأَةُ إِلَى الْمَرْأَةِ فِي الثَّوْبِ الْوَاحِدِ
338 صحيح مسلم كتاب الحيض باب تحريم النظر إلى العورات
قال النووي وَكَذَلِكَ يَحْرُمُ عَلَى الرَّجُلِ النَّظَرُ إِلَى وَجْهِ الْأَمْرَدِ إِذَا كَانَ حَسَنَ الصُّورَةِ سَوَاءٌ كَانَ نَظَرُهُ بِشَهْوَةٍ أَمْ لَا سَوَاءٌ أَمِنَ الْفِتْنَةَ أَمْ خَافَهَا هَذَا هُوَ الْمَذْهَبُ الصَّحِيحُ الْمُخْتَارُ عِنْدَ الْعُلَمَاءِ الْمُحَقِّقِينَ نَصَّ عَلَيْهِ الشَّافِعِيُّ
