Answered by Ustadh Sufyan Qufi
Does swallowing mucus invalidate my fast?
In the name of Allah, Most Compassionate, Most Merciful.
No, swallowing mucus that has reached one’s mouth through one’s nose or one’s throat does not invalidate one’s fast. [Shurunbulali, Maraqi al-Falah] This is because by doing so, one is not entering anything into the body cavity which would break the fast.
The Messenger of Allah (peace and blessings upon him) said, “The fast is broken from what enters [the body].” [Musnad Abu Ya’la by way of Nasb al-Raya]
And Allah knows best.
