[Machine] I heard Sa'id ibn al-Musayyib saying that my aunt Khawla bint Hakeem al-Sulamiyah asked the Messenger of Allah ﷺ about a woman who experiences nocturnal emission, and he commanded her to perform ghusl (ritual bath).  

سَمِعْتُ سَعِيدَ بْنَ الْمُسَيِّبِ يَقُولُ سَأَلَتْ خَالَتِي خَوْلَةُ بِنْتُ حَكِيمٍ الْسُلَمِيَّةُ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَحْتَلِمُ «فَأَمَرَهَا أَنْ تَغْتَسِلَ»  

"O Messenger of Allah! Allah is not shy to tell the truth. Inform me: if a women sees in a dream what men see should she perform Ghusl from that?" The Messenger of Allah ﷺ said to her: "Yes." 'Aishah said: "I expressed my displeasure and said: 'Does a woman see that?' The Messenger of Allah ﷺ turned to me and said: 'May your right hand be covered with dust! How else would (her child) resemble her?'" (Using translation from Nasāʾī 196)   

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا أَخْبَرَتْهُ أَنَّ أُمَّ سُلَيْمٍ أُمَّ بَنِي أَبِي طَلْحَةَ دَخَلَتْ عَلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهَ إِنَّ اللَّهِ لَا يَسْتَحْيِي مِنَ الْحَقِّ أَرَأَيْتَ الْمَرْأَةَ تَرَى فِي النَّوْمِ مَا يَرَى الرَّجُلُ أَتَغْتَسِلُ؟ قَالَ «نَعَمْ» فَقَالَتْ عَائِشَةُ فَقُلْتُ أُفٍّ لَكِ أَتَرَى الْمَرْأَةُ ذَلِكَ؟ فَالْتَفَتَ إِلَيْهَا رَسُولُ اللَّهِ ﷺ فَقَالَ «تَرِبَتْ يَمِينُكِ فَمِنْ أَيْنَ يَكُونُ الشَّبَهُ»  

[Machine] Umm Salamah entered upon the Messenger of Allah ﷺ while Umm Salimah was with him. The woman said, "Do women see in their dreams what men see?" Umm Salamah said, "May your hands be covered in dust, O Umm Salimah. You have caused disturbance among women." The Prophet ﷺ replied, supporting Umm Salimah, "No, indeed it is your hands that should be covered in dust, for you have asked about what concerns you when you see water. Therefore, you should perform ablution." Umm Salimah asked, "Do women have water available?" He replied, "Yes, how can they resemble boys? They are the counterparts of men."  

دَخَلَتْ عَلَى رَسُولِ اللَّهِ ﷺ أُمُّ سُلَيْمٍ وَعِنْدَهُ أُمُّ سَلَمَةَ فَقَالَتْ الْمَرْأَةُ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ؟ فَقَالَتْ أُمُّ سَلَمَةَ تَرِبَتْ يَدَاكِ يَا أُمَّ سُلَيْمٍ فَضَحْتِ النِّسَاءَ فَقَالَ النَّبِيُّ ﷺ مُنْتَصِرًا لِأُمِّ سُلَيْمٍ «بَلْ أَنْتِ تَرِبَتْ يَدَاكِ إِنَّ خَيْرَكُنَّ الَّتِي تَسْأَلُ عَمَّا يَعْنِيهَا إِذَا رَأَتِ الْمَاءَ فَلْتَغْتَسِلْ» قَالَتْ أُمُّ سَلَمَةَ وَلِلنِّسَاءِ مَاءٌ؟ قَالَ «نَعَمْ فَأَنَّى يُشْبِهُهُنَّ الْوَلَدُ؟ إِنَّمَا هُنَّ شَقَائِقُ الرِّجَالِ»
