عَنْ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا تُبَاشِرُ الْمَرْأَةُ الْمَرْأَةَ حَتَّى تَصِفَهَا لِزَوْجِهَا كَأَنَّمَا يَنْظُرُ إِلَيْهَا زَادَ فِي رِوَايَةٍ إِلَّا أَنْ يَكُونَ بَيْنَهُمَا ثَوْبٌ
It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: A woman should not sleep with another woman and then describe her to her husband in such a way as if he is looking at her. In another narration, these additional words are mentioned: unless there is a cloth between the two of them.
