[Machine] The Messenger of Allah ﷺ said, "A woman should not have a private conversation with another woman, and then speak ill of her to her husband as if he is looking at her." This is narrated in Sahih Al-Bukhari from the Hadith of Al-A'mash.  

قَالَ رَسُولُ اللهِ ﷺ لَا تُبَاشِرُ الْمَرْأَةُ الْمَرْأَةَ ثُمَّ تَنْعَتُهَا لِزَوْجِهَا كَأَنَّهُ يَنْظُرُ إِلَيْهَا أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ الْأَعْمَشِ
