The Ruling on Smoking and Trading in it

Question :

What is the ruling on smoking?

Answer:

Smoking is forbidden because it is evil and contains many harmful things. Allah, Most Glorified, Most High has only permitted foods and drinks which are good and pure (At-Tayyibat) for His creatures. He has forbidden evil and impure things (Al-Khaba'ith) for them. Allah, Most Glorified, Most High says:
"They ask you (O Muhammad) what is lawful for them (as food). Say: "Lawful unto you are At-Tayyibat [all kinds of Halal (lawful-good)

And He, Most Glorified says, in describing His Prophet, Muhammad ﷺ in Surat Al-A'raf.
"He commands them for Al-Ma'rüf (i.e. Islamic Monotheism and all that Islam has ordained); and forbids them from Al-Munkar (i.e., disbelief, polytheism of all kinds, and all that Islam has forbidden); he allows them as lawful At-Tayyibat (i.e., all good and lawful as regards things, deeds, beliefs, persons and foods). and prohibits them as unlawful Al-Khaha'ith (i.e., all evil and unlawful as regards things, deeds, beliefs, persons and foods)."

Smoking of all forms is not from among the good and pure things; rather it is from the evil and impure things. Likewise, all forms of intoxicants are from among the evil and impure things. And it is not permissible to smoke cigarettes, cigars, pipes etc., nor to sell them, nor to trade in them, like alcoholic drinks. It is an obligation upon anyone who smoked them or dealt in them to hasten towards repentance to Allah, Most Glorified and to express regret for what has passed, and to make the firm intention not to return to it. Whoever sincerely repented, Allah will turn to him with forgiveness, as Allah, the Almighty, the All- Powerful says:
"And all of you beg Allah to forgive you all, O believers, that you may be successful."

And He, Most Glorified, Most High says:
"And verily, I am indeed forgiving to him who repents, believes (in My Oneness, and associates none in worship with Me) and does righteous good deeds, and then remains constant in doing them (till his death).

And Allah is the Granter of success.
