Writing aayaat of
    the Qur’aan, washing the words and drinking the water
Question

                Some people write aayaat of the
      Qur’aan then wash them and drink the water. If anyone objects, they say, “It is
      the word of Allaah and we are seeking healing through it.” Is this action
      permissible?
Praise be to Allah.This action is permissible, i.e., if a person writes
    Qur’aan in a kind of “ink” that it is permissible to drink (e.g., saffron),
    then puts what he has written into water and shakes it, then drinks it. Some of the salaf
    used to do this, using vessels such as plates and the like. If someone does this, he has a
    precedent in the salaf or early generations of Islam. He may also take as evidence the
    general meaning of the aayah (interpretation of the meaning):
“And We send down from the Qur’aan that which is a healing
    and a mercy to those who believe…” [al-Isra’ 17:82]
If a person seeks healing from the Qur’aan in this manner and
    benefits from it (and there is no text to prove that doing so is haraam and no bad results
    occur), then it comes under the general meaning of this aayah.
