Yes, smoking cigarettes or any form of tobacco does not invalidate the physical act of fasting, but it is strongly discouraged during fasting in Islam. While it doesn’t break the fast from a technical standpoint, smoking involves inhaling smoke and engaging in a habit that is harmful to one’s health. Fasting in Islam not only involves abstaining from food and drink but also encompasses a broader concept of self-discipline and purification. Many Islamic scholars and health experts advise against smoking, especially during fasting, due to its detrimental health effects. Smoking is harmful to the body, and fasting is an opportunity for Muslims to improve their physical and spiritual well-being. Therefore, it is recommended to refrain from smoking while fasting to fully benefit from the fast and to promote a healthier lifestyle.
