Sahih
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنِ ابْنِ مَسْعُودٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تُبَاشِرُ الْمَرْأَةُ الْمَرْأَةَ لِتَنْعَتَهَا لِزَوْجِهَا كَأَنَّمَا يَنْظُرُ إِلَيْهَا " .
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.”
