Ibn Masu’d reported the Apostle of Allaah ﷺ as saying “ A woman should not rub her body directly with the body of another woman so that she describes it to her husband as if he were looking at her.” (Using translation from Abū Dāʾūd 2150)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ «لَا تُبَاشِرِ الْمَرْأَةُ الْمَرْأَةَ فَتَصِفَهَا لِزَوْجِهَا كَأَنَّهُ يَنْظُرُ إِلَيْهَا»  

[Machine] "Do not let a woman be alone with another woman, nor a man with another man."  

«لَا تُبَاشِرِ الْمَرْأَةُ الْمَرْأَةَ وَلَا الرَّجُلُ الرَّجُلَ»
