What is the legitimate Islamic comment on the understanding that the rules of Tajwid have a psychological dimension that evokes deep meanings when reciting the Quran, and are there any ancient or modern works that have explored this aspect?

Undoubtedly, the recited Qur’an has a stronger impact on hearts. Its recitation and adherence to the rules of Tajwid help in contemplating it. This impact is further enhanced by the beauty of the reciter's voice, observance of pauses, and contemplation of meanings. The Prophet, peace and blessings be upon him, said: "Indeed, among the people with the most beautiful voices in the Qur’an is he whom, when you hear him recite, you think he fears Allah." The Prophet, peace and blessings be upon him, listened to the recitation of Abu Musa al-Ash'ari and praised it.
