عَنْ يَزِيدَ بْنِ أَبِي سُمَيَّةَ سَمِعْتُ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُ يَقُولُ: سَأَلَتْ أُمُّ سُلَيْمٍ وَهِيَ أُمُّ أَنَسِ بْنِ مَالِكٍ فَقَالَتْ: يَا رَسُولَ اللَّهِ! تَرَى الْمَرْأَةُ فِي الْمَنَامِ مَا يَرَى الرَّجُلُ؟ فَقَالَ لَهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((إِذَا رَأَتِ الْمَرْأَةُ ذَلِكَ وَأَنْزَلَتْ فَلْتَغْتَسِلْ))
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that Sayyida Umm Sulaym (may Allah be pleased with her), who was the mother of Sayyiduna Anas bin Malik (may Allah be pleased with him), said: O Messenger of Allah! That which a man sees in a dream, if a woman sees the same, then what? The Prophet (peace and blessings be upon him) said: When she sees this and experiences ejaculation, then she should perform ghusl (ritual bath).
