Narrated Zainab bint Um Salama:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا يَحْيَى ، عَنْ هِشَامٍ ، قَالَ أَخْبَرَنِي أَبِي ، عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ ، عَنْ أُمِّ سَلَمَةَ ، أَنَّ أُمَّ سُلَيْمٍ، قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ اللَّهَ لاَ يَسْتَحِي مِنَ الْحَقِّ، هَلْ عَلَى الْمَرْأَةِ غُسْلٌ إِذَا احْتَلَمَتْ قَالَ " نَعَمْ إِذَا رَأَتِ الْمَاءَ ". فَضَحِكَتْ أُمُّ سَلَمَةَ فَقَالَتْ أَتَحْتَلِمُ الْمَرْأَةُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " فَبِمَ شَبَهُ الْوَلَدِ " .
Um Sulaim said, "O Allah's Messenger (ﷺ)! Verily Allah is not shy of (telling you) the truth. Is it essential for a woman to take a bath after she had a wet dream (nocturnal sexual discharge)?" He said, "Yes, if she notices discharge. On that Um Salama laughed and said, "Does a woman get a (nocturnal sexual) discharge?" He said, "How then does (her) son resemble her (his mother)?"
