How to Quit Smoking Cigarettes – Easy Method
Action Plan
1. Niyyah – Make Your Intention It 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).
2. Change Your Habits – 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.
3. Find Alternatives -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).
