What is the ruling on writing verses from the Qur'an in ink and then having a sick person drink it?

The questioner : Scholars in Sudan do this, meaning they write the Qur'an in ink and have some of their followers drink it, or something like that. Similarly, they write Qur'anic verses on small pieces of paper and give them to the patient to inhale; what is the evidence that prohibits this?

The Shaykh : ...the scholarly evidence, but its transmission from the Salaf is not authentic, so we do not consider it prescribed.
