Does inhaling incense and pleasant aromas break the fast, and what is its ruling in the four schools of thought?

Jurists differed concerning the ruling on inhaling incense for a fasting person. The Hanafis, Malikis, and Hanbalis held that inhaling incense and intentionally allowing it to reach the throat breaks the fast. They based this on the possibility of abstaining from it, unless it was involuntary or the person was an incense maker, in which case it is excused due to the difficulty of abstaining. The Shafi'is, however, believe that inhaling incense does not invalidate the fast, even if it reaches the interior, because the arrival of an effect, such as taste and smell through sniffing, does not break the fast. As for sniffing pleasant scents like musk, roses, and the like, it does not break the fast by agreement of the madhhabs.
