حَدَّثَنَا دَاوُدُ بْنُ رُشَيْدٍ حَدَّثَنَا صَالِحُ بْنُ عُمَرَ حَدَّثَنَا أَبُو مَالِکٍ الْأَشْجَعِيُّ عَنْ أَنَسِ بْنِ مَالِکٍ قَالَ سَأَلَتْ امْرَأَةٌ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ الْمَرْأَةِ تَرَی فِي مَنَامِهَا مَا يَرَی الرَّجُلُ فِي مَنَامِهِ فَقَالَ إِذَا کَانَ مِنْهَا مَا يَکُونُ مِنْ الرَّجُلِ فَلْتَغْتَسِلْ
صحیح مسلم · Hadith 711
Anas b. Malik reported that Umm Sulaim narrated it that she asked the Messenger of Allah ( صلی اللہ علیہ وسلم ) about a woman who sees in a dream what a man sees (sexual dream). The Messenger of Allah (may peace be upon bi m) said: In case a woman sees that, she must take a bath. Umm Sulaim said: I was bashful on account of that and said: Does it happen? Upon this the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Yes (it does happen), otherwise how can (a child) resemble her? Man's discharge (i. e. sperm) is thick and white and the discharge of woman is thin and yellow; so the resemblance comes from the one whose genes prevail or dominate.
