Mishkat al-Masabih
Jabir reported God's Messenger as saying, “A man must not spend the night in the house of a woman who has been married unless he is her husband or a close relative.” Muslim transmitted it.
وَعَنْ جَابِرٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِلَّا لَا يبتن رَجُلٌ عِنْدَ امْرَأَةٍ ثَيِّبٍ إِلَّا أَنْ يَكُونَ ناكحا أَو ذَا محرم» . رَوَاهُ مُسلم
