A woman asked the Messenger of Allah (way peace be upon him) about a woman who sees in her dream what a man sees in his dream (sexual dream). He (the Holy Prophet) said: If she experiences what a man experiences, she should take a bath.

سَأَلَتِ امْرَأَةٌ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ فِي مَنَامِهِ فَقَالَ إِذَا كَانَ مِنْهَا مَا يَكُونُ مِنَ الرَّجُلِ فَلْتَغْتَسِلْ

She asked the Messenger of Allah about a woman who sees in her dream that which a man sees. He said: "She does not have to take a bath unless she has an orgasm, just as man does not have to take a bath unless he has an orgasm."

أَنَّهَا سَأَلَتْ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ فَقَالَ لَيْسَ عَلَيْهَا غُسْلٌ حَتَّى تُنْزِلَ كَمَا أَنَّهُ لَيْسَ عَلَى الرَّجُلِ غُسْلٌ حَتَّى يُنْزِلَ

She asked the Messenger of Allah about a woman who sees in her dream that which a man sees. He said: "She does not have to take a bath unless she has an orgasm, just as man does not have to take a bath unless he has an orgasm." (Using translation from Ibn Mājah 602)

أَنَّهَا سَأَلَتِ النَّبِيَّ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ؟ فَقَالَ لَيْسَ عَلَيْهَا غُسْلٌ حَتَّى يَنْزِلَ الْمَاءُ كَمَا أَنَّ الرَّجُلَ لَيْسَ عَلَيْهِ غُسْلٌ حَتَّى يُنْزِلَ

"If water is released then let her perform Ghusl." (Using translation from Nasāʾī 195)

أَنَّ أُمَّ سُلَيْمٍ سَأَلَتْ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ؟ قَالَ «إِذَا أَنْزَلَتِ الْمَرْأَةُ فَلْتَغْتَسِلْ»

" عَنْ خَوْلَةَ بِنْتِ حَكِيمٍ أَنَّهَا سَأَلَتِ النَّبِيَّ ﷺ عَنِ المَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ، فَقَالَ: إِنَّهُ لَيْسَ عَلَيْهَا غُسْلٌ حَتَّى تُنْزِلَ، كَمَا أَنَّ الرَّجُلَ لَيْسَ عَلَيْهِ غُسْلٌ حَتَّى يُنْزِلَ".
