Ibn Mas'ud reported God’s Messenger as saying, “A woman must not come in close contact with another and then describe her to her husband, for that is as if he were looking at her.” (Bukhari and Muslim)

وَعَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُبَاشِرُ الْمَرْأَةُ الْمَرْأَةَ فَتَنْعَتُهَا لِزَوْجِهَا كَأَنَّهُ ينظر إِلَيْهَا»
