عَنْ أَبِي هُرَيْرَةَ قَالَ: جَاءَ رَجُلٌ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: إِنِّي تَزَوَّجْتُ امْرَأَةً مِنَ الْأَنْصَارِ قَالَ: «فَانْظُرْ إِلَيْهَا فَإِنَّ فِي أَعْيُنِ الْأَنْصَارِ شَيْئًا» . رَوَاهُ مُسْلِمٌ

Abu Sa'id reported God’s Messenger as saying, “A man must not look at a man’s private parts or a woman at a woman’s, and a man must not come close to a man in one garment or a woman to a woman in one garment.” Muslim transmitted it.
