Is it correct to say that the heart mentioned in the Quran is the heart of the soul, and that humans think with their souls, given the limited capacity of the human body to comprehend sciences and knowledge that will increase and not change in Paradise, which might lead to its saturation and inability to comprehend more, or to its growth in size in a way that hinders movement, contrary to what has been stated that the people of Paradise will abide eternally and their knowledge will remain?

It is well-known among scholars that the human body itself will be resurrected and raised in the Hereafter. It has been established that people will recognize each other, and it is known that what is recognized is the form of the body by which they knew one another in this world. Surat Qaf explicitly indicates that Allah Almighty will resurrect this very body, which obeyed or disobeyed, to be either rewarded or punished. Al-Ghazali declared the philosophers disbelievers for denying the resurrection of bodies and their gathering, describing their belief as incompatible with Islam and as a belief that falsifies the prophets. As for what was mentioned about the inhabitants of Paradise bathing in one spring and drinking from another, thereby transforming their bodies and what they contain, there is no evidence to support this.
