Niyyah - Make Your IntentionIt is first recommended to make the firm intention, from deep in your heart, to give up this evil habit. Trust in Allah's words: "...When you have taken a decision, put your trust in Allah. For Allah loves those who put their trust in Him. If Allah help you, none can overcome you; if He forsakes you, who is it - after that - that can help you? In Allah, then, let believers put their trust" (Qur'an 3:159-160).
Change Your HabitsSecondly, you must avoid situations where you are used to smoking, and people who do so around you. For example, if you have certain friends who gather together to smoke, make a choice to stay away from that environment for the time being. At a vulnerable stage, it is too easy to relapse by having "just one." Remember, tobacco causes a physical addiction and you must stay away completely.
Find AlternativesThirdly, drink a lot of water and keep yourself busy in other endeavors. Spend time in the mosque. Play sports. Pray. Spend time with your family and non-smoking friends. And remember the words of Allah: "And those who strive hard in Our Cause, We will certainly guide them to Our Paths, for verily Allah is with those who do right” (Qur'an 29:69).

If You Live With a SmokerIf you live with or are friends with smokers, first of all encourage them to quit, for the sake of Allah, their health, and their deen. Share with them the information here, and offer support through the difficult process of quitting.
Remember that we will each face Allah alone, however, and we are responsible for our own choices. If they refuse to quit, you have the right to protect your own health and the health of your family. Do not allow it in the house. Do not allow it in enclosed quarters with your family.
If the smoker is a parent or other elder, we should not neglect to take care of our health out of "respect." The Qur'an is clear that we are not to obey our parents in things which are forbidden by Allah. Gently, but firmly, advise them of the reasons for your own choices.
