Question: What is the penalty for a smoker according to the Sharee’ah?
Response: The smoker is one who is engaging in something haraam, since smoking [itself] is haraam, and we have previously mentioned the evidences as to its prohibition. So, based upon this, if the smoker knows it is haraam, then he is persisting in something which is considered from amongst the minor sins. [However], persisting in something which is considered from amongst the minor sins in itself renders the sin a major sin. So, as a result, he is regarded as a faasiq (open sinner), and immoral and not to be regarded [both in speech and actions]. This is because that which is widely accepted amongst the scholars is that whoever persists in something which is regarded as a minor sin, then he is a faasiq, and his speech or actions are not to be regarded in all that which requires uprightness.
So it is upon this man to fear his Lord and refrain from smoking which severely affects the wealth, the body and the [practice of the] religion.
