Does Intentionally Swallowing a Solid Mucus That Enters One’s Throat Invalidate Fast?

Hanafi Fiqh

Answered by Mawlana Ilyas Patel


I sniffed solidified mucus (i.e., snot) from my nose, which went directly down my throat/entered my mouth and was intentionally swallowed. Is it going to break my fast?


In the Name of Allah, the Most Merciful and Compassionate.

I pray you are in good faith and health.

Solidified mucus and snot are considered unavoidable substances and do not invalidate one’s fast, even if done intentionally. This is because one is not entering anything into the body cavity, which would break the fast.

However, one should avoid this from happening and spit it out.

What are Unavoidable Substances?

This applies to things one cannot guard oneself against, and if one were to do so, it would entail unbearable hardship.

Unavoidable Substances

Examples include:

  •  Water that remains in the mouth and nose from wudu.
  •  Possible dampness when one is showering.
  •  Mucus.
  •  Snot.
  •  Saliva.
  •  Saliva that may end up on the lips from talking.
  •  Bugs and flies.
  •  Dust.
  •  Smog from the traffic.
  •  Flour from a flour mill.
  •  What may be in the air when working as a construction worker.

The examples above are not exhaustive of what can be considered an unavoidable substance. [‘Ala’uddin Ibn ‘Abidin, al-Hadiyya al-‘Ala’iyya]
