Recite the Qur'an: The Prophet (Sallallahu alaiyhi wassallam) said, "... Qur'an is a remedy for illnesses of the mind" (Bukhari). "The echo of sound has a medical effect and is now widely utilized," says Dr. Greenberg. "The recitation of or listening to the Qur'an has an effect on the body, the heart and the mind! It is said that the letter Alif echoes to the heart and the letter Ya' to the pineal gland in the brain." Dr Ahmed El Kadi of Akber Clinic (Panama City, FL) conducted and published the effects of listening to Qur'anic recitation on physiological parameters (i.e., the heart, blood pressure, and muscle tension), and reported improvement in all factors, irrespective of whether the listener was a Muslim or a non-Muslim, Arab or non-Arab. Obviously, it can be postulated that those who understand and enjoy the recitation with a belief in it will get maximum benefits," writes Dr Athar.
