The Quran says رَجُل 23 times and ٱمْرَأَة 23 times. A father contributes exactly 23 chromosomes. A mother contributes exactly 23 chromosomes.
This page is about the biology. The number 23 is not arbitrary it is the precise contribution of each parent to every human cell. This was unknown when the Quran was written. It was confirmed 1,323 years later using microscopy that didn't exist until the 20th century.

How many chromosomes does a father contribute to his child?
Every human cell contains chromosomes the structures that carry genetic information. They come in pairs, one from each parent. How many does the father provide?

Every human alive carries the chromosomes of two parents combined.
23 + 23 = 46 in every cell of the human body

When did science first confirm the correct human chromosome count of 46?
Before modern microscopy, scientists guessed wrong. The true count 23 from each parent, 46 total was only established when staining and imaging techniques became precise enough to see individual chromosomes clearly.

years between the Quran and the chromosome discovery
610–632 CE The Quran is revealed and compiled. The word for "man" (رَجُل) carries exactly 23 semantic roles. The word for "woman" (ٱمْرَأَة): exactly 23.
7th–19th century Chromosomes are completely unknown. Scientists have no way to see them. The scientific consensus through the 1950s was that humans have 48 chromosomes the wrong number.
1952 Rosalind Franklin images DNA. The field begins to understand genetic structure, but the exact chromosome count remains uncertain.
1955 Tjio & Levan use improved microscopy to confirm the correct count: 46 total 23 from the father, 23 from the mother.

23 father's chromosomes
23 mother's chromosomes
The word for man and the word for woman each appear with exactly 23 semantic roles. A father provides exactly 23 chromosomes. A mother provides exactly 23. The Quran was compiled in 632 CE a full 1,323 years before chromosomes were even known to exist.

Not a coincidence. A precise alignment across 1,323 years.
The Quran uses the word for "man" exactly 23 times and "woman" exactly 23 times. A father contributes 23 chromosomes to every child. A mother contributes 23. The text was fixed in 632 CE. The biology was confirmed in 1955. There was no number to aim for. Chromosomes were completely unknown. The alignment is exact, reproducible, and impossible to explain by accident.
