Yahya related to me from Malik from Ibn Shihab from Urwa ibn az- Zubayr that Umm Sulayman said to the Messenger of Allah ﷺ "Should a woman do ghusl when she experiences the same as a man in her sleep?" The Messenger of Al lah said to her, "Yes, she should do ghusl. "A'isha said to her, "Shame on you! Does a woman see that?" (i.e. a liquid.) The Messenger of Allah ﷺ said to her, "May your right hand be full of dust. From where does family resemblance come?"  

قَالَتْ لِرَسُولِ اللَّهِ ﷺ الْمَرْأَةُ تَرَى فِي الْمَنَامِ مِثْلَ مَا يَرَى الرَّجُلُ أَتَغْتَسِلُ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ نَعَمْ فَلْتَغْتَسِلْ فَقَالَتْ لَهَا عَائِشَةُ أُفٍّ لَكِ وَهَلْ تَرَى ذَلِكَ الْمَرْأَةُ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ تَرِبَتْ يَمِينُكِ وَمِنْ أَيْنَ يَكُونُ الشَّبَهُ  

Yahya related to me from Malik from Hisham ibn Urwa from his father from Zaynab bint Abi Salama that Umm Salama, the wife of the Prophet ﷺ said, "Umm Salama, the wife of Abu Talha al-Ansari, came to the Messenger of Allah ﷺ and said, 'Messenger of Allah! Allah is not ashamed of the truth-does a woman have to do ghusl if she has had an erotic dream?' He said, 'Yes, if she sees any liquid.' "  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ جَاءَتْ أُمُّ سُلَيْمٍ امْرَأَةُ أَبِي طَلْحَةَ الأَنْصَارِيِّ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ اللَّهَ لاَ يَسْتَحْيِي مِنَ الْحَقِّ هَلْ عَلَى الْمَرْأَةِ مِنْ غُسْلٍ إِذَا هِيَ احْتَلَمَتْ فَقَالَ نَعَمْ إِذَا رَأَتِ الْمَاءَ
