Answered by Shaykh Yusuf Weltch
Will using essential oils break our fast? Is it the same for diffusing in a diffuser?
In the Name of Allah, the Most Merciful and Compassionate
The fast is broken when a tangible substance enters the body. [Ibn ‘Abidin, Radd al-Muhtar]
If you use essential oils topically in does not break the fast. However, if you diffuse the essential oil and directly breath in the mist from the diffuser the fast breaks.
Note that if this was does unintentionally or in a state that one didn’t remember that they were fasting the fast remains valid.
Thus there is a clear difference between smelling the scent of something and a tangible essence (in this case mist) of something entering the body by one’s own doing.
[Ibn ‘Abidin, Radd al-Muhtar citing al-Imdad]
