What is the ruling on breaking the fast with smoke?

Question:
May Allah reward you, Honorable Shaykh. The questioner asks: What is the ruling on the one who breaks his fast with smoke? Is his fasting valid or invalid? May Allah reward you with good.

Answer:
This is, in truth, harm to himself. Smoke is harmful, a deadly poison, and evil. So he harms himself with this foul substance after a great act of worship by committing a sin. This is not permissible; it is not permissible. Smoking is not permissible; it is forbidden, absolutely, always. But smoking at the time of breaking the fast is even more strictly forbidden because it is after an act of worship, after fasting, and at a time of seeking forgiveness and repentance. The Muslim afflicted with smoking should leave it for Allah the Exalted and repent to Allah, and leave it, for it is better for him in his religion and his worldly life. It is better for him in his religion because he leaves a forbidden act in obedience to Allah the Exalted, and it is better for him in his worldly life because he preserves his health and avoids the disease that smoke brings him. It is obligatory for the Muslim to have determination and strength and to leave this bad, ugly habit in which there is no good. Yes.
