It was narrated from Zainab, the daughter of Umm Salamah, that :Her mother Umm Salamah said: "Umm Sulaim came to the Prophet and asked him about a woman who sees in her dream something like a man sees. He said: 'Yes, if she sees water (discharge), let her take a bath.' I said: 'You have embarrassed the women. Do women experience wet dreams?' The Prophet said: 'May your hands be rubbed with dust, how else does her child resemble her?'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ، عَنْ أُمِّهَا أُمِّ سَلَمَةَ، قَالَتْ جَاءَتْ أُمُّ سُلَيْمٍ إِلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ فَسَأَلَتْهُ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ قَالَ " نَعَمْ إِذَا رَأَتِ الْمَاءَ فَلْتَغْتَسِلْ " . فَقُلْتُ فَضَحْتِ النِّسَاءَ وَهَلْ تَحْتَلِمُ الْمَرْأَةُ قَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ " تَرِبَتْ يَمِينُكِ فَبِمَ يُشْبِهُهَا وَلَدُهَا إِذًا " .
