What is the ruling on treating oneself with water over which verses have been recited?

Question:
Is it permissible to treat oneself by drinking water in which verses from the Noble Qur'an have been placed?

Answer:
Yes, there is nothing wrong with reciting over water and drinking it, or using it for a bath as well. This is a form of medicine, a form of treatment. The Qur'an is healing and guidance. The Prophet (peace and blessings be upon him) used to treat people with the Qur'an, and his Companions did the same. It is reported in Sunan Abu Dawud with a good chain of narration from the Prophet (peace and blessings be upon him) that he recited over a vessel for Thabit ibn Shamas, in which water was placed, and he poured it over him, may Allah's peace and blessings be upon him. Also, a group of people recited over a person who had been bitten by a venomous creature, blowing over him with al-Fatihah.
Therefore, seeking healing through the Qur'an, whether by reciting it over the sick or in water, is all permissible.
