Prohibition of Meeting a non-Mahram Woman in Seclusion
وَعَنْ عُقْبَةَ بْنِ عَامِرٍ رَضِيَ اللَّه عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: "إِيَّاكُمْ وَالدُّخُولَ عَلَى النِّسَاءِ"، فَقَالَ رَجُلٌ مِنَ الأَنْصَارِ: أَفَرَأَيْتَ الْحَمْوَ؟ قَالَ: "الْحَمْوُ الْمَوْتُ" ((مُتَّفَقٌ عَلَيْهِ)). الحمو قريب الزوج كأخيه، وابن أخيه، وابن عمه.
'Uqbah bin 'Amir (May Allah be pleased with him) said: The Messenger of Allah (ﷺ) said, "Avoid (entering a place) in which are women (uncovered or simply to mix with them in seclusion)." A man from the Ansar said, "Tell me about the brother of a woman's husband." He replied, "The brother of a woman's husband is death." [Al- Bukhari and Muslim].
