Gender determination Hadith – Scientific Evidence for Islam
There are two Hadiths at which Islam haters jump with joy. This is mainly because of a mistranslation and misconception due to the mistranslation.
The Hadiths are as follows:
أن امرأة قالت لرسول الله صلى الله عليه وسلم : هل تغتسل المرأة إذا احتلمت وأبصرت الماء ؟ فقال ” نعم ” فقالت لها عائشة : تربت يداك . وألت . قالت فقال رسول الله صلى الله عليه وسلم ” دعيها . وهل يكون الشبه إلا من قبل ذلك . إذا علا ماؤها ماء الرجل أشبه الولد أخواله . وإذا علا ماء الرجل ماءها أشبه أعمامه ” .
Annam ra’ata, qaalat li Rasoolillah sal Allahi alayhi wasallam hal taghtasilul mar’atu izaH talamat wa absaratil maa’ faqaala na’m. Faqaalat laha Aishatu tarbat yadaaki wa ullat. Qaalat faqaala Rasoolullahi sal Allahi alayhi wasallam da’eeha wa hal yakoonush shabahu illa min qibali zaaliki iza ‘ala maa’uha maa’ ar rajuli ashbahal waladu akhwaalahu wa iza ‘alaa maa’ ar rajuli maa’ aha ashbaha a’amaamahu.
“Aisha may Allah be pleased with her reported: a woman asked the Messenger of Allah peace be upon him “Is a woman required to perform ghusl (i.e. wash completely as if showering as per the prescribed way) if she had a sexual dream and notices wetness?
He responded: Yes. Aisha said to her: May your hand be covered with dust and injured (i.e. she blamed the woman for asking an embarrassing question). However, Prophet Muhammed peace be upon him said: Leave her; resemblance happens because of it.
When her water is dominant, the born child resembles his maternal uncles but if sperm of the man was dominant, the born child should resemble his paternal uncles.” [Sahih Muslim, book 3, Hadith 37]
The Hadith is usually translated as follows:
A woman came to the Messenger of Allah peace be upon him and inquired: Should a woman wash herself when she sees a sexual dream and sees (the marks) of liquid? He said: Yes. ‘A’isha said to her: May your hand be covered with dust and injured. She narrated:
The Messenger of Allah peace be upon him said: Leave her alone. In what way does the child resemble her but for the fact that when the discharge contributed by woman prevails upon that of man, the child resembles the maternal family, and when the discharge of man prevails upon that of woman the child resembles the paternal family.
” ماء الرجل أبيض وماء المرأة أصفر. فإذا اجتمعا، فعلا مني الرجل مني المرأة ، أذكرا بإذن الله . وإذا علا مني المرأة مني الرجل ، آنثا بإذن الله
Maa’ ur rajuli abyadu wa maa’ ul mar’ati asfar fa izaj tama’aa fa’ala maniyyur rajuli maniyyul mar’ati azkara bi-iznillahi wa iza ‘alaa maniyyul mar’ati maniyyur rajuli anathaa bi-iznillah.
The water of the man is white, and the water of the woman is yellow. When they get together, if the discharge of the man (i.e. sperm) become above the discharge of the woman, the child is male, by the permission of Allah, and if the discharge of the woman becomes above the discharge of the man (i.e. sperm), the child is a female by the permission of Allah. [Sahih Muslim, book 3, Hadith 38]
The Hadith is usually translated as follows:
The reproductive substance of man is white and that of woman yellow, and when they have sexual intercourse and the male’s substance prevails upon the female’s substance, it is the male child that is created by Allah’s Decree, and when the substance of the female prevails upon the substance contributed by the male, a female child is formed by the Decree of Allah.
The criticism against the Hadiths is that the gender of the child is dependent on the chromosome of the sperm cell and has nothing to do with the discharges of either the man or the woman. The proper translations should clarify this misconception; however, we shall discuss further below. The first Hadith discusses resemblance and the second one gender.
This narration goes along with the genetic science that resemblance of children is explained through the theory of dominance where superior genes prevail over the child. It is also known that sperm is alkaline whereas women’s ejaculated fluid is acidic. In order for sperm to reach the woman’s egg it has to go through the woman discharge.
Thus, when acidic and alkaline fluids meet, alkaline fluids either neutralize, or overpower acidic fluid and hence cause sperm to preserve its nature [i.e. man’s genes become weak] or that alkaline discharge effects the fluid and makes it weak. This can be one of the interpretations and understanding.
One may argue that though it may be possible, it is not convincing. However, as this is supposed to be scientifically examined, we only can reach this decision based on facts and certainty. One major point that causes all this confusion about this Hadith, and hence some people find it problematic, is that they tend to immediately understand the word water of women to mean ejaculated fluid that happens due to intimacy or arousal.
If we pay attention to the words used in this Hadith, we find great findings i.e. Prophet Muhammed peace be upon him used the word water (maa’) in reference to the liquid of women and he did not specify it any further. We have to understand what the Prophet peace be upon him meant with water of women as he did not specify it.
It is true that he did not specify it, but he actually described it when he said in another narration the water of women is yellow and thin. So, what is that fluid that has such a description?
It is known that ejaculated discharge due to arousal or intimacy is white. The only liquid that is yellow is actually called follicular fluid which is discharged without a relation to copulation or arousal, and it is directly related to pregnancy. It comes out with a thin layer called follicle of which inside there is a small egg that combines with the sperm of man during fertilization, and this has to happen in order for a child to be created.
It must be noted that neither the questioner nor answerer [i.e., Prophet Muhammed peace be upon him] intended to explain the how of this process. Rather, he explained why children sometimes resemble their fathers and some other times, resemble their mothers.
This is proven and well explained in another Hadith when Prophet Muhammed peace be upon him clearly stated that resemblance is purely genetic when a woman delivered a black boy and the man doubted that he his wife may slept with another man as none of the family was black.
When he explained it to the man, he told him that genetics of great grandfather may affect grandchildren.
From this we learn that it is obvious that Prophet Muhammed peace be upon him acknowledged that determining the how of the matter was left for us to discover; the Hadith only provides us with the key, which is the answer to why this happens.
To sum it up:
The Hadith only addresses the topic of resemblance
Science states that ejaculated liquid of women is irrelevant to childbearing or resemblance
The Hadith only addresses the topic of resemblance
The Hadith calls the liquid of women as water without specifying its nature or type
In another Hadith, this water has been described as yellow and thin
Science states that only follicular fluid has such description whereas other ejaculated liquids are white in color
Science states that follicular fluid has a layer inside the egg that is involved in the process because men have semen that includes sperm and women have follicular fluid that includes the egg.
Based on this, the Hadith becomes clear and understood. Unnecessary further digging is fruitless since Prophet Muhammed peace be upon him did not explain genetic science. He simply answered how a child sometimes resemble his father’s side and at other times, his mother’s side.
If this is kept in mind, one realizes that what confuses a person is due to the how of such process while the Hadith speaks of why. Therefore, we learn that one should not add assumptions or take the Hadith out of its context and then examine it according to these faulty assumptions.

The second Hadith:
Some scholars like Ibn al-Qayyim questioned the authenticity of the words ‘it becomes male…it becomes female’ and said it is a possible mistake made by one of the narrators in the chain as the preserved text states about resemblance.
It is important to pay attention to the used words in the Hadith. The key words are highlighted below for further clarification.
The water of the man is white, and the water of the woman is yellow. When they get together, if the sperm of the man become above the sperm of the woman, the child is male, by the permission of Allah, and if the sperm of the woman becomes above the sperm of the man, the child is a female by the permission of Allah.
Regarding yellow discharge It is known that ejaculated discharge due to arousal or intimacy is white. The only liquid that is yellow is called follicular fluid which is discharged without a relation to copulation or arousal, and it is directly related to pregnancy.
It comes out with a thin layer called follicle of which inside there is a small egg that combines with the sperm of man during fertilization, and this must happen for a child to be created. The yellow discharge is INTERNAL and NOT EXTERNAL
Notes on the Hadith:
The word above here means dominant as this is one of the known meanings of the word above and has been used in Quran to mean dominant and controlled.
The first half of the Hadith referred to the man and woman’s liquids as water while in the second half it became more specific and is referred to as the sperm.
We already know that Prophet Muhammed peace be upon him mentioned in other Hadiths that the water of women is involved in process of fertilization. We learn that this water has a description that does not befit ejaculated fluids since ejaculated fluids are white in color whereas he described the color as yellow and thin.
The sound understanding of this text is that Prophet Muhammed peace be upon him referred to the male and female chromosome of the sperm cell of the man (X as the female chromosome and Y as the male chromosome).
Based on this, Prophet Muhammed peace be upon him meant that when the male factor is dominant then it is a boy but when the female factor is dominant, then it is a girl.
This is what science states, and this is the sound understanding that one should have because the text can be understood in various ways, and we know that authentic texts must be in agreement with agreed-upon facts.
What caused the confusion? People understood it in a certain way; they assumed that the sperm word used in this Hadith refer to a man and a woman while as a matter of fact, Prophet Muhammed peace be upon him referred to the sperm of the man only which is always a carrier of male and female chromosomes. This is supported by the fact that the word sperm is always exclusively for man when women’s liquid is always called water only.
As for this Hadith from Sahih al-Bukhari 3329:
That says the resemblance is based upon which one releases it first. Sahih al-Bukhari 3329: Why does a child resemble its father, and why does it resemble its maternal uncle” Allah’s Messenger peace be upon him said, “Gabriel has just now told me of their answers.” `Abdullah said, “He (i.e., Gabriel), from amongst all the angels, is the enemy of the Jews.”
Allah’s Messenger peace be upon him said, “The first portent of the Hour will be a fire that will bring together the people from the east to the west; the first meal of the people of Paradise will be Extra-lobe (caudate lobe) of fish-liver.
As for the resemblance of the child to its parents: If a man has sexual intercourse with his wife and gets discharge first, the child will resemble the father, and if the woman gets discharge first, the child will resemble her.
Did that mean that only gender depends on this and not resemblance?
Clarification about Sahih al-Bukhari 3329
The Hadith uses the word maa’ (water) which is not necessarily ejaculate fluid but internal fluids as well. Which is like the Hadith posted above:
When her water is dominant, the born child resembles his maternal uncles but if sperm of the man was dominant, the born child should resemble his paternal uncles’. In the Hadith from Bukhari, ‘dominant’ is not used but ‘before’ is used.
Umm Salama (r) questioned whether women get a discharge (in Sahih Bukhari 3328).
Basically, she understood it to be external while the Prophet (s) clarified that it happens to everyone which implies that it is internal; otherwise, she would’ve objected against it.
How the jew would know that this was right when he said only a prophet would know the answer.
There can be several ways that the Jew knew that this was the right answer:
- Jews had remnants of other forms of revelation not a part of the Torah and these could be either direct revelations (or their translations) or commentaries (oral or Talmudic). What should be remembered is that Bibles were not mass produced and only a handful of learned men had their own copies while others
(also, a handful of people) learned these through those knowledgeable ones who had copies and these people would have bits and pieces here and there. If they had some form of remaining revelation that mentioned a sign of the last Prophet, then this wouldn’t be surprising.
- The Prophet peace be upon him informed us that true dreams are 1/46th of revelation. It could be that this one particular Jew had seen a sign for which he got the confirmation.
- It is even possible that the former Jew did not know the answer. We do not know of many things, for example in mathematics, but accept them when a teacher explains to us. How do we know that the teacher explained correctly?
It is easy to spot a liar or someone faking it – if one does not know something and makes something up on the spot, it is usually easy to spot the lie. Truth comes without hesitation, without knots in the tongue, and without a problem.
Perhaps the truthfulness of Prophet Muhammad peace be upon him was seen from these sings and the Jew(s) did not actually know of the answer.
- When Makkans wanted to prove the Prophet peace be upon him wrong, they sought advice of the Jews who told them to ask about some incidents of the past (sleepers of the cave, Zulqarnayn, soul).
They themselves did not know of these events with certainty but still asked the Prophet peace be upon him and would have judged him based on the answer. It is sometimes easy to tell that someone is telling the truth even if one does not know the truth himself.
Indeed, Allah knows best.

 The Hadith in Sunan Ibn Majah Vol. 3, Book 9, Hadith 2002 is as follows:
عَنْ أَبِي هُرَيْرَةَ، قَالَ جَاءَ رَجُلٌ مِنْ بَنِي فَزَارَةَ إِلَى رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ . فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ” هَلْ لَكَ مِنْ إِبِلٍ ” . قَالَ نَعَمْ . قَالَ ” فَمَا أَلْوَانُهَا ” . قَالَ حُمْرٌ . قَالَ ” هَلْ فِيهَا مِنْ أَوْرَقَ ” . قَالَ إِنَّ فِيهَا لَوُرْقًا . قَالَ ” فَأَنَّى أَتَاهَا ذَلِكَ ” . قَالَ عَسَى عِرْقٌ نَزَعَهَا . قَالَ ” وَهَذَا لَعَلَّ عِرْقًا نَزَعَهُ ” . وَاللَّفْظُ لاِبْنِ الصَّبَّاحِ
It was narrated that Abu Hurairah said: “A man from Banu Fazarah came to the Messenger of Allah, and said: ‘O Messenger of Allah, my wife has given birth to a black boy! The Messenger of Allah said: ‘Do you have camels?’ He said: ‘Yes.’
He said: ‘What color are they?’ He said: ‘Red.’ He said: ‘Are there any grey ones among them?’ He said: ‘Yes, there are some grey ones among them.’ He said: ‘Where does that come from?’ He said: ‘Perhaps it is hereditary.’ He said: ‘Likewise, perhaps this is hereditary! “
As for people who disagree about the scientifically miraculous nature of this Hadith-
- You can Google the theory of dominance and read more about the dominant and recessive gene types.
- The word is ‘maa’ which means water and the article above explains this.
- No one is claiming a miracle anywhere.
- You did not understand the alkaline, acidic, and resemblance and gender determination part at all; try going through it again because what you wrote does not contradict what is written in the article.
- For follicular fluid, if you don’t like the word discharge, then use some other like ‘formed’, ‘released’ and so on but try to grasp the essence of what is written and not just make up your mind to refute senselessly.
