The Ruling on Smoking and Selling Tobacco

Question:
May Allah reward you. This questioner sent a set of questions. He says: I hope you will deliver a guiding word to every smoker, explaining the ruling on smoking and selling it. May Allah reward you with good.

Answer:
Tobacco is a foul and harmful substance, and it has no benefit in any way. It is foul in its smell, foul in its taste, and foul in its effect and color on the one who uses it. You will find its bad effect and bad color in his mouth, lips, and teeth. Moreover, and greater than that, it is foul and causes deadly diseases, such as cancer in its various forms, as doctors have established. It also corrupts the chest and what the tobacco stores up. If you were accustomed to lighting a fire in a room, a large room, and you repeated lighting fires in it, its walls and door would become black. So what would happen to the narrow chest of a human being from using this foul substance?
Also, it is a means of wasting money without any benefit, because he buys it with a lot of money and gains nothing, but only harm. And if innocent people are harmed by tobacco when they are in a car, or in a room, or in the street, meaning that people are harmed by this tobacco because it is foul, then what about the one who uses it?
So from these aspects, it is forbidden. It is not permissible to use it, and it is not permissible to sell it. Its price is forbidden, because when Allah forbids something, He forbids its price. So selling it is forbidden, buying it is forbidden, growing it is forbidden, and trading in it and bringing it in, all of these are forbidden. And it is a foul earning. Yes.
