My husband is a righteous man who is consistent in prayer, fasting, and reading the Qur'an, but he smokes cigarettes. Does this detract from his good deeds?

Question:
May Allah reward you with good and do you well. You say: I have a righteous man who does not commit to praying and fasting, but he is always consistent in reading the Noble Qur'an. He is a good man who does not harm anyone; on the contrary, he is the one who is subjected to harm from others. But the Shaykh has the habit of smoking cigarettes. Is this forbidden? And does it detract from his good deeds?

Answer:
There is no doubt that something from al-Bukhari is [missing], because it is [missing] the flesh, and because it has no benefit for the person; it neither fattens nor satisfies hunger. Rather, it is a bad habit, and because it binds the person to addiction, so he cannot abstain from it, and because it exhausts money without any benefit returning to the person. On the contrary, it exhausts money in what is harmful and disease-causing, so it [missing] his body.
When the minds of the wise [missing] on the person in his days of trial, until he sees as good what is not good. It is only ugly habits, blind imitation, the absence of intellect, and correct thinking. So it is obligatory for the one who begins to smoke to [missing] to Allah and to return to Allah's guidance, and to leave smoking. Smoking is a sin and forbidden, and it detracts from the reward of the one who smokes, without doubt, and it [missing] him because it is forbidden. What is forbidden is what its doer is punished for; it is what its doer is punished for, and it [missing] its leaver. This is what is forbidden. So if he does it, he does the forbidden, and by that his reward is diminished. Yes.
