How can one explain cases of healing that occur outside the context of the Qur'an, such as the Christian woman who was healed by placing a cross, or patients who were cured by poetic incantations, believing them to be the Qur'an? Does this mean that the Qur'an is not a healing in itself, but rather that healing is contingent upon belief and inner conviction?

A distinction must be made between a karamah (divine miracle granted to a righteous person) and istidraj (gradual enticement towards perdition). A karamah is an extraordinary event manifested by God through a righteous servant, whereas istidraj appears through an infidel or a transgressor. Not everyone benefits from the Quran as a healing, for that requires sincerity, faith, and certainty. The statement that "healing is what we believe in our subconscious mind" is incorrect. Furthermore, some who claim healing in the name of Christ or the cross might be promoting disbelief and istidraj.
