Can mental illness (an organic disease) be cured with the Quran?

The belief that healing through the Quran is exclusive to certain ailments like epilepsy and possession, to the exclusion of physical diseases, is a common misconception. The Quran is a general healing for all spiritual and bodily ailments. This is confirmed by Allah's saying: (And We send down from the Quran that which is a healing and a mercy to those who believe) and His saying: (Say, "It is for those who believe, a guide and a healing.") Moreover, the hadith of Abu Sa'id Al-Khudri showed that reciting Al-Fatihah is a cure for a scorpion sting. For healing to occur through the Quran, it is required that both the reciter and the one seeking recitation have certainty and sincere reliance on Allah.
