What is the ruling on someone who repeatedly swore an oath, saying: "By Allah, every time I light a cigarette, or smoke a cigarette, I will fast two days from the coming week," then broke that oath? And does the ruling differ between lighting a cigarette and smoking it? And what if he smokes more than one cigarette in the week? And is fasting two days sufficient for all of them, or for each cigarette? And what is the punishment for not fulfilling the expiation of the oath in the afterlife, and does repentance and seeking forgiveness prevent it?

The questions indicate the inquirer's intention to continue smoking and break his oath. The remedy for this is sincere repentance and cessation of smoking. Expiation is repeated with the repetition of the breaking of the oath if the oath implies repetition, whether verbally, by intention, or by custom. The intention of the swearer particularizes his oath.

Understanding the first question: "By Allah, every time I light a cigarette, or smoke a cigarette...", the inquirer breaks his oath by lighting the cigarette or smoking it, unless he intended that lighting it means smoking it. If he lights it and smokes it, he owes one expiation.

As for the second question, it appears that the expiation is repeated with every cigarette. If the number of mandatory fasting days in a week reaches eight days or more, then fasting the entire week is sufficient. If the intention was that the expiation would be repeated with the repetition of weeks, then the inquirer owes one expiation if he does not fast.

As for the third question, intentionally abandoning expiation while being able to perform it is a sin. Repentance that fulfills its conditions prevents punishment, but mere seeking of forgiveness while persisting in the sin is up to Allah.

Conclusion: The solution to the problem is complete cessation of smoking.
