Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
It should be known that all smells, either good or bad, whatever strong they are, do not invalidate the fast.
Responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
Smelling the balm or scent does not invalidate one’s fast. So, you don’t need to worry about it.
However, I would urge you to focus on the inner meanings of the fast which is to stay focused on mindfulness of Allah and shunning the sins Allah has forbidden, including the outward and the inward.
Allah Almighty knows best.
