Um Sulaim said, "O Messenger of Allah 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)?" (Using translation from Bukhārī 6091)
قَالَتْ أُمُّ سُلَيْمٍ يَا رَسُولَ اللهِ إِنَّ اللهَ لَا يَسْتَحْيِي مِنَ الْحَقِّ هَلْ عَلَى الْمَرْأَةِ مِنْ غُسْلٍ إِذَا احْتَلَمَتْ؟ قَالَ نَعَمْ إِذَا رَأَتِ الْمَاءَ فَضَحِكَتْ أُمُّ سَلَمَةَ قَالَتْ أَتَحْتَلِمُ الْمَرْأَةُ؟ فَقَالَ النَّبِيُّ ﷺ فَبِمَ يُشْبِهُ الْوَلَدُ؟
