Qur’anic Evidence

Translation: "And it is He who produced for you hearing (Sam') and vision (Absar) and intellect (Af'idah)..."
(Surah Al-Mu’minun 23:78)

Linguistic Analysis: In the Qur'an, "Hearing" (As-Sam') almost always precedes "Sight" (Al-Absar). Classical scholar Al-Razi noted this order suggests a priority in function or development.

Neuroscientific Reality

Modern Developmental Neurobiology confirms this specific chronological sequence:

• Hearing (In Utero): The inner ear (Cochlea) and the auditory nerve are fully myelinated and functional by the 24th week of gestation. The fetus can hear internal sounds and the mother's voice.
• Sight (Post-Natal): The visual cortex (V1) and optic nerve are not fully myelinated at birth. An infant's vision is blurry and only develops focus weeks after birth.

Qur’anic Evidence

Translation: "Yes. We are Able even to reconstruct his fingertips."
(Surah Al-Qiyamah 75:4)

Tafsir Insight: Why fingertips? Al-Qurtubi notes that the verse emphasizes the reconstruction of the finest details of the human body, not just major bones.

The Science of Dermatoglyphics

In 1892, Sir Francis Galton established the science of fingerprints. He proved that:

• Uniqueness: No two individuals, not even identical monozygotic twins, have the same fingerprints. While twins share DNA, the pressure of amniotic fluid during development creates unique ridges on the fingertips.
• Permanence: The pattern remains unchanged from the 4th month of fetal life until death.

Qur’anic Evidence

Translation: "Who created you, then proportioned you, then balanced you."
(Surah Al-Infitar 82:7)

Key Term: 'Adalak (Balanced You): This implies establishing equilibrium.

Physiological Mechanism: Homeostasis

The human body is an engineering marvel of Homeostasis (a term coined by Walter Cannon in 1926). This refers to the body's ability to maintain stable internal conditions despite external changes.

• Thermoregulation: Keeping body temperature at 37°C.
• pH Balance: Keeping blood acidity strictly between 7.35 and 7.45.
• Bilateral Symmetry: The skeletal and muscular balance allowing upright bipedal locomotion.

Qur’anic Evidence

Translation: "They have hearts (Qulub) wherewith they understand not..."
(Surah Al-A'raf 7:179)

Modern Neurocardiology

While the brain is the primary center of computation, modern science recognizes the Intrinsic Cardiac Nervous System (ICNS), often called the "Little Brain" of the heart.

• The heart contains over 40,000 neurons.
• It communicates with the brain via the Vagus nerve, influencing perception and emotional processing (Amygdala).

Refuting Ancient Myths

To verify the source of this knowledge, we must look at what is absent:

• Galen’s Errors (2nd Century): Galen believed the liver pumped blood and the heart generated heat. The Qur'an avoids these physiological errors completely.
• Aristotle’s Errors (4th Century BC): Aristotle believed the brain was merely a radiator to cool the blood. The Qur'an, however, links the "Forelock" (Frontal Lobe) to decision-making and lying (Surah Al-Alaq 96:16).
• The Sequence: The consistent ordering of "Hearing then Sight" matches the biological timeline of myelination, a fact impossible to observe without 20th-century imaging tools.
