Hastening to the inclusion of inhaled substances, such as smoke or vapors from food, does complicate matters further. While consensus among scholars inclines towards the stance that inhaling smoke does not invalidate the fast, intentionally inhaling vaporized substances—like aerosols or tobacco—certainly poses risks and raises ethical questions about one’s commitment to spiritual discipline.
3. Extraordinary Circumstances
In the realm of Shia jurisprudence, the concept of extraordinary circumstances plays a vital role in understanding the invalidators of the fast. Any circumstance that leads to extreme hardship or difficulty can offer an exception to the obligation of fasting. Illness constitutes the most prevalent reason for exemption. Should an individual feel unwell or weak—whether due to chronic conditions or temporary illness—they may bypass the fast, with the condition of making amends through either compensatory fasting or providing food to the needy, known as fidya.
