Chapter 7: Women are obliged to perform ghusl if they emit fluid - كتاب الحيض
حَدَّثَنَا دَاوُدُ بْنُ رُشَيْدٍ، حَدَّثَنَا صَالِحُ بْنُ عُمَرَ، حَدَّثَنَا أَبُو مَالِكٍ الأَشْجَعِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ سَأَلَتِ امْرَأَةٌ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ فِي مَنَامِهِ فَقَالَ " إِذَا كَانَ مِنْهَا مَا يَكُونُ مِنَ الرَّجُلِ فَلْتَغْتَسِلْ " .
Anas b. Malik reported:
A woman asked the Messenger of Allah (way peace be upon him) about a woman who sees in her dream what a man sees in his dream (sexual dream). He (the Holy Prophet) said: If she experiences what a man experiences, she should take a bath.
