What is obligatory upon one who swore not to return to smoking and then did return?

Question:
This questioner, who used the initials (M. M. S) as a code for his name, says: O Shaykh! My question is that I swore to quit the habit of smoking, but I returned to it a second time. I also swore that if I returned to it—meaning if I returned to smoking a second time—I would fast for two consecutive months. I was unable to resist myself in this matter and returned to smoking. Does this mean I must fast for two months? Or is it only the expiation for an oath? And is it permissible for me to feed poor people instead of fasting?

Answer:
You must repent to Allah, and you must pay the expiation. You must repent to Allah for returning to smoking, because it is forbidden, an evil, and a vile thing. You must pay the expiation for the oath. If the intention behind the fasting was to deter yourself from it, then you must pay the expiation for the oath when you returned to it, which is feeding ten poor people, or clothing them, or freeing a slave. If you cannot do that, you must fast for three days. This is the expiation for the oath. It is obligatory for you to quit smoking, because it is forbidden, an evil, and a vile thing. Therefore, it is obligatory to be cautious of it, to repent to Allah from it, and not to sit with its people so that they do not lead you into it. Beware of sitting with them, seek help from your Lord, and be hopeful of good, if Allah wills. Yes.
