Questioner:

What is the ruling on using an asthma pump [during while fasting] due to trouble breathing?

Shaykh Muqbil bin Hādī al-Wādiʿī:

It is apparent that it does not contain food or drink. Does it contain water O’ brothers? Does a person sense water or is water sprayed from it? So I don’t know if it would invalidate the fast.
