God has said in the Quran about one of the evil unbelievers who forbade the Prophet Muhammad from praying at the Kaaba

No! If he does not stop, We will take him by the naseyah (front of the head), a lying, sinful naseyah (front of the head)!
(Quran, 96:15-16)

Figure 12: Functional regions of the left hemisphere of the cerebral cortex. The prefrontal area is located at the front of the cerebral cortex. (Essentials of Anatomy & Physiology, Seeley and others, p. 210.)

So, this area of the cerebrum is responsible for planning, motivating, and initiating good and sinful behavior and is responsible for the telling of lies and the speaking of truth. Thus, it is proper to describe the front of the head as lying and sinful when someone lies or commits a sin, as the Quran has said, “...A lying, sinful naseyah (front of the head)!”

Scientists have only discovered these functions of the prefrontal area in the last sixty years, according to Professor Keith L. Moore
