Islam apologist, Dr Al Zeiny writes:

Until fairly recently, it was thought that a baby's sex was determined by the mother's cells. Or at least, it was believed that the sex was determined by the male and female cells together. The Quran is the only ancient book that states that sex is determined by the (male) sperms.

"He has created both sexes, male and female from a drop of a (male) sperm which has been ejected." (The Qur'an, 53:45-46)

This claim is repeated by Dr. Zakir Naik in his book "The Quran and Modern Science" (link). 

ANALYSIS

  • This claim has only been made very recently by Islam apologists for the first time.
  • Otherwise, not a single Muslim Quran interpreter of the last 14 centuries came to this conclusion from this verse. 
  • There is nothing in this verse which is telling about sex determination.
  • This verse is simply telling only one thing the process of creation of both sexes starts with the sperm when it is ejected.

As compared to this deceptive conjecture of these modern Islam apologists, we have Muhammad himself, who is telling the Islamic concept of sex determination in the following Hadith (tradition). 

Sahih Muslim, Book of Menstruation:
... قَالَ ‏"‏ مَاءُ الرَّجُلِ أَبْيَضُ وَمَاءُ الْمَرْأَةِ أَصْفَرُ فَإِذَا اجْتَمَعَا فَعَلاَ مَنِيُّ الرَّجُلِ مَنِيَّ الْمَرْأَةِ أَذْكَرَا بِإِذْنِ اللَّهِ وَإِذَا عَلاَ مَنِيُّ الْمَرْأَةِ مَنِيَّ الرَّجُلِ آنَثَا بِإِذْنِ اللَّهِ ‏"‏ 
.... 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 Jew said: What you have said is true; verily you are an Apostle. He then returned and went away. 

Therefore, Muhammad has himself denied the Islam apologists here about the process of sex determination of the fetus. 

Muhammad made double Scientific Mistakes in this Hadith:

  • Firstly, the reproductive substance of a woman is not yellow. It is a wonder that Muslims still consider Muhammad to be a true messenger of God even after this huge scientific blunder. 
  • Secondly, Muhammad is claiming that the sex of the child is determined if the father's or mother's substance prevails, which is again wrong according to science, while it is the father's chromosome which determines the sex of the fetus. 

But as we know that Muhammad was doing this Drama of revelation at his own, and making all these stories and claims on his own, therefore, many "human mistakes & contradictions" occurred in these stories. Let us look at the following Hadith. 

Sahih Muslim, Book of Destiny:
... Allah's Messenger said: When forty-two nights pass after the semen gets into the womb, Allah sends the angel and gives him shape. Then he creates his sense of hearing, sense of sight, his skin, his flesh, his bones, and then says: My Lord, would he be male or female? And your Lord decides as He desires and the angel then puts down that also

Therefore, Muhammad not only contradicted those modern Islam apologists, but in this Hadith, Muhammad contradicted himself too by giving a different reason regarding the determination of the sex of the foetus (i.e. Allah decided it Himself and sex determination has nothing to do with male sperm). 

PS:

We posted a Hadith above where Muhammad claimed that the reproductive substance of a woman is yellow. This is a fatal scientific mistake.

Sahih Muslim, Book of Menstruation:
... قَالَ ‏"‏ مَاءُ الرَّجُلِ أَبْيَضُ وَمَاءُ الْمَرْأَةِ أَصْفَرُ فَإِذَا اجْتَمَعَا فَعَلاَ مَنِيُّ الرَّجُلِ مَنِيَّ الْمَرْأَةِ أَذْكَرَا بِإِذْنِ اللَّهِ وَإِذَا عَلاَ مَنِيُّ الْمَرْأَةِ مَنِيَّ الرَّجُلِ آنَثَا بِإِذْنِ اللَّهِ ‏"‏ 
....  He (the Holy Prophet) said: The reproductive substance of man (Arabic: مَاءُ الرَّجُلِ) is white and that of woman (Arabic: مَاءُ الْمَرْأَةِ) yellow, and when they have sexual intercourse and the male's substance (chromosomes and genes) prevails upon the female's substance (chromosomes and genes), 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 Jew said: What you have said is true; verily you are an Apostle. 

But modern Islam apologists are now trying to use deception, in order to change the meaning of "female substance" by claiming that it does not refer to female discharge during sex (which is not yellow, but white), but it refers to the central part of the female ovum, which is yellow (like egg yolk of hens is yellow):

However, such an interpretation is impossible, since in another Hadith:

  • Firstly, Muhammad claimed that it was quite visible (and the genetic material inside the ovum isn’t)
  • Secondly, Muhammad claimed that a man's substance is "thicker", while of woman's is "thinner", which is not possible if we assume the yellow part of the ovum (egg), which is as thick as the sperm (actually it is thicker than male sperm). 
  • In both Hadiths, the word used for man's substance is مَاءَ الرَّجُلِ , and the word used for woman's substance is مَاءَ الْمَرْأَةِ. Therefore, it is not possible for Islam apologists to cast more doubts about this scientific error of Muhammad. 

Sahih Muslim, The Book of Menstruation:
أُمَّ سُلَيْمٍ حَدَّثَتْ أَنَّهَا، سَأَلَتْ نَبِيَّ اللَّهِ صلى الله عليه وسلم عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِذَا رَأَتْ ذَلِكِ الْمَرْأَةُ فَلْتَغْتَسِلْ ‏"‏ ‏.‏ فَقَالَتْ أُمُّ سُلَيْمٍ وَاسْتَحْيَيْتُ مِنْ ذَلِكَ قَالَتْ وَهَلْ يَكُونُ هَذَا فَقَالَ نَبِيُّ اللَّهِ صلى الله عليه وسلم ‏"‏ نَعَمْ فَمِنْ أَيْنَ يَكُونُ الشَّبَهُ إِنَّ مَاءَ الرَّجُلِ غَلِيظٌ أَبْيَضُ وَمَاءَ الْمَرْأَةِ رَقِيقٌ أَصْفَرُ فَمِنْ أَيِّهِمَا عَلاَ أَوْ سَبَقَ يَكُونُ مِنْهُ الشَّبَهُ ‏"‏ ‏.‏Anas b. Malik reported that Umm Sulaim narrated it that she asked the Messenger of Allah 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  said: Yes (it does happen), otherwise how can (a child) resemble her? Man's discharge (Arabic: مَاءَ الرَّجُلِ) is thick and white and the discharge of woman (Arabic: مَاءَ الْمَرْأَةِ) is thin and yellow; so the resemblance comes from the one whose genes prevail or dominate

Also, see:

Sunnan Ibn Majah, The Book of Purification:
It was narrated from Zainab, the daughter of Umm Salamah, that :Her mother Umm Salamah said: "Umm Sulaim came to the Prophet and asked him about a woman who sees in her dream something like a man sees. He said: 'Yes, if she sees water (discharge), let her take a bath.' I said: 'You have embarrassed the women. Do women experience wet dreams?' The Prophet said: 'May your hands be rubbed with dust, how else does her child resemble her?'"

Even women were able to tell that Muhammad made a wrong claim about their sexual discharge during the dream.

Moreover, do fluids released in a woman's orgasm determine the resemblance of children to parents, or is that genetic information carried by the egg and sperm and determined when they meet?

The answer is simple, as an orgasm does not have anything to do with the egg, which is what carries the genome of the woman. 

Actually, discharges of man and woman are even not needed anymore, and one sperm fertilizes one egg mechanically through syringe, but still babies resemble to the mother and father.

...but your task is still not finished.

Dear seeker of truth,
Reading about the flaws in a belief system is only the first step. To truly break free from indoctrination and reach a final, unshakable conclusion, you must apply these four critical tests to what you've just read.

Test 1: Divine Revelation or Human Drama?

The Core Challenge:
God does not appear before us, nor do His angels manifest themselves, and He performs no miracles today like the claims made in the tales of ancient times. Despite this absence, we are still demanded to recognise God through His "commands"  only. 
Let us examine these commands, and see if they give the impression of Divine Revelation, or of "Human Drama."

Please reflect:

  • Do the teachings in this article display flawless wisdom, justice, consistency, and coherence that could only come from an Omniscient Creator?
  • Or do they resemble the kinds of laws, contradictions, exceptions, and inconsistencies that one would expect from ordinary human decision-making?

Test 2: Would These Same Arguments Also Defend a False Prophet?

Imagine a man in a different era who claims to be a prophet. He marries multiple women, claims divine permission for his personal desires, issues harsh punishments, and makes scientific errors—acting exactly like Muhammad. How would you distinguish this hypothetical false prophet from Muhammad?

The truth is, Islamic apologists would easily spot him as a fraud or a cult leader, using the exact same logical critiques you just read. Yet, when Muhammad does these exact same things, apologists invent endless rationalizations to defend him.

The Rule of Logic: If your defense of a prophet works equally well to defend a proven fraud or a cult leader, your defense is not based on evidence. It is based on "special pleading", giving one man a free pass that you would never give anyone else.

Test 3: Just One Confirmed Error Is Enough

Islam makes an extraordinary claim that Allah exists, is absolutely perfect, and cannot make even a single mistake. Therefore, if even one confirmed error, injustice, or flaw is found in Islam, its entire claim to divine perfection collapses. The remaining 99.99% of the religion cannot save that claim. You cannot simply argue, "But everything else is correct."

Test 4: The "Unbiased AI" Evaluation

Artificial Intelligence models are programmed to be highly deferential toward major world religions. If you ask an AI to critique the Quran, it will  treat Islamic theology as unquestionable facts rather than claims to be tested. This creates a false "tie" in debates.

To get a truly objective, logical evaluation of the article you just read, you must force the AI to drop its religious deference. Read the prompt below, then click the button to copy it. Paste it into your AI chat before asking it to analyze the article.

When reviewing the article, keep the following principles in mind:
The Qur'an and Hadith cannot be used as evidence of their own divine origin. They are claims whose origin is being examined. Your task is to evaluate whether the Qur'an, Sunnah, and Islamic legal system are better explained as Divine Revelation or as human authorship. Therefore:
• Treat the Qur'an and Hadith as claims, not proof.
• Evaluate the article using logic, internal consistency, factual accuracy, and principles of justice.
• Treat scholarly interpretations as arguments in favor of Islam, not as binding authority.
Based on these principles, answer this question: Do the objections raised in the article expose flaws that reason and justice cannot reconcile, or do the strongest Muslim apologetic arguments successfully answer those objections?

Note: The AI’s response is not a final judgement. The final decision must be made by you, using your own reason and understanding.
