Is My Fast Still Valid if I’m Unsure About Swallowing Food That Comes to My Mouth?

Hanafi Fiqh

Answered by Ustadh Sufyan Qufi


I burped and felt a little food come back up my throat fasting. I went to spit it out and rinse my mouth, but while rinsing, I purposefully let some water reach the back of my throat, not to drink it, but to help me get any remaining regurgitation out of my mouth.

I’m not sure if any water entered my stomach. Also, I wasn’t sure if I should have just spit out the regurgitation. Is my fast valid?


In the name of Allah, Most Compassionate, Most Merciful,

I pray this finds you in the best of states.

Doubts Regarding One’s Worship

Yes, your fast is valid because you are unsure if the water you have used to rinse your mouth was swallowed.

“Certainty is not lifted by a doubt.” [Ibn Nujaym, al-Ashbah wa’l Nadha’ir; Majallat al-Ahkam al-`Adiliyya]

This means that if one is certain about something, such as the validity of our worship, with this being the basic assumption for all human actions, then we will keep assuming it valid until certain that it was not. Mere possibilities and even likelihoods do not change this.

Vomiting While Fasting

You didn’t have to spit out the food that has reached your mouth because it was in small quantity.

As long as the amount of food that has come up in your mouth doesn’t fill your mouth your fast is not broken by swallowing it back. [Ibn ‘Abidin, Radd al-Muhtar]

May  Allah Most High grant you the best of this world and the next. Please keep us in your du’as!

And Allah knows best.
