The Quran on the Cerebrum
The Qur’an on the Cerebrum
1. Introduction
The cerebrum is the largest part of the human brain, responsible for higher mental functions such as thinking, planning, decision-making, and controlling voluntary movement. Modern neuroscience confirms that the front part of the cerebrum—the prefrontal cortex—plays a crucial role in behavior, judgment, and truthfulness. Remarkably, the Qur’an, revealed over 1,400 years ago, makes a reference to this specific area of the brain in a way that aligns with modern scientific findings.
2. Qur’anic Reference to the Forehead
In the context of warning against arrogance and falsehood, the Qur’an says:
“No! If he does not desist, We will surely drag him by the forelock – a lying, sinful forelock.”
(Surah Al-‘Alaq 96:15-16)
Here, the forelock refers to the front area of the head, just above the forehead—beneath which lies the prefrontal region of the brain.
3. The Prefrontal Cortex in Modern Science
Neuroscientific research over the last century has shown that the prefrontal cortex:
-
Controls decision-making and planning
-
Influences social behavior and moral judgment
-
Plays a role in telling the truth or lying
-
Governs self-control and conscious actions
When this part of the brain is damaged, a person may lose the ability to control their impulses, make sound decisions, or behave morally.
4. Alignment Between Qur’an and Science
The Qur’an’s description of the forelock as “lying” and “sinful” fits perfectly with the role of the prefrontal cortex. While the physical forehead itself cannot lie, the brain region just behind it is directly responsible for deliberate lying, immoral behavior, and conscious wrongdoing.
5. Purpose of the Qur’anic Mention
The Qur’an often refers to physical features in a way that points to deeper spiritual and moral truths. In this verse, the reference to the forelock serves two purposes:
-
Spiritual warning: Condemning arrogance and rebellion against Allah.
-
Scientific insight: Pointing to a brain region that modern science now recognizes as central to moral and decision-making processes.
6. Conclusion
The Qur’an’s reference to the “lying, sinful forelock” is remarkably consistent with current neuroscience, which identifies the prefrontal cortex as the area controlling conscious moral choices and dishonest actions. This harmony between revelation and science serves as a reminder that the One who revealed the Qur’an is the same One who created the human brain.
