Answered by Shaykh Faraz Rabbani
What is the ruling regarding swallowing phlegm, accidentally or otherwise while fasting? Can you please give an example as well?
Answer:
Assalamu alaikum,
Swallowing phlegm from within the mouth does not invalidate the fast in the Hanafi school, even if done intentionally. [Shurunbulali, Maraqi]
However, it is recommended to avoid swallowing phlegm, [ibid.] in a dignified manner, when reasonably possible.
Wassalam,
Faraz Rabbani
