The Reasoning of the Heart in the Holy Quran, Truth or Medical Error?

The purpose of religious doubts is to prove the conflict between medical findings and religious teachings. In this context, a book entitled "Criticism of the Qur'an" has been published, in which the author, in part of the second chapter, criticizes the verses of the Holy Qur'an that attribute wisdom to the heart, and citing the wisdom of Nahjal Balagha 105, he claims that because in the past, human beings did not know What is the brain inside the skull? This medical mistake entered the Quran from the environment. This research intends to criticize the claims made.

This research was done by descriptive-analytical method and relying on library documents. The research method in this study is content analysis.

In the Holy Qur'an, when talking about reasoning and understanding facts by the heart, it does not mean the heart of the flesh. Rather, it means the speaking soul, which can be the origin of human traits and characteristics.

Knowing the functioning of the brain was obvious in the past, and the instrumental role of the brain in reasoning and thinking is also mentioned in the narrations. In confirmation of the provisions contained in Hikmat 105, new evidences of the functions of the heart in transmitting certain emotions have been discovered. Also, the speaking soul of a human being is called "heart" when the word of truth affects it and turns it upside down.
