The cigarettes people smoke nowadays is harmful. Allah forbade it when he says: “Those who follow the Messenger, the unlettered prophet, whom they find written in what they have of the Torah and the Gospel, who enjoins upon them what is right and forbids them what is wrong and makes lawful for them the good things and prohibits for them the evil…” Q7:157.
People disregarded this fact when they were told until the world medical Practitioners confirmed that smoking is harmful and extremely dangerous to humans. This includes the one inhaled by smokers and the smoke inhaled by people in their surroundings. Therefore, we warn all Muslims against this evil.
