Sahih Bukhari Vol. no. 1 in the Book of Adhan Hadith no. 855 where the Prophet said that
“Anyone who eats garlic or onion, they should stay away from us and stay away from the mosque”
Prophet said that, you know, that don’t come to the mosque after having garlic or onion because it gives bad breath. When you are smoking the breath is worse then onion or garlic so based on this Hadith therefore garlic and onion doesn’t become haraam, it becomes Makhrooh so based on this Hadith scholars give the Fatwa that smoking is Makhrooh
But now after science has advanced we have come to know that smoking is nothing but it’s a slow poisoning. Tobacco in any form whether in smoking cigarettes whether bedi whether tobacco in Huqqa whether chewing tobacco all forms of tobacco contain nicotine and tar and we know its nothing but slow poisoning. That’s the reason most of the non-Muslims also, they agree that smoking is Haraam. Not only the Muslim world even the non-Muslims. That’s the reason they put a statutory warning on the cigarette packs, they put a statutory warning saying “Cigarette smoking is injurious to health” or in some countries it mentions “General Surgeon’s Warning” or “Surgeon General’s warning: Smoking is injurious to health”.
And anyone gives an add whether in newspaper or in the magazine or television it is compulsory that they have to highlight this statement “Smoking is Injurious to Health” so I am not talking about the Muslim world even the non-Muslim world agrees that smoking is nothing but slow poisoning.
And today according to statistics the World Health Organization says that every year more than more than 4 million people die only because of smoking. And if you count the other forms of tobacco it will be much more. And today medical science tells us and even I had learnt when I was doing my medicine in a medical collage that more than 90% of the lung cancer deaths are only due to smoking. Whether cigarette or bedi whatever it is. 25% of the cardio vascular deaths are only because of smoking. 70 to 75% of Bronchitis and related deaths are only because of smoking. Smoking is nothing but slow poisoning. It blackens your lips, blackens your gums, blackens your fingertips, it damages your lips, it damages your esophagus, it damages your stomach and it can cause constipation, it can cause loss of appetite, it can cause loss of libido, your sexual power gets suppressed, it can cause immunity to the drugs you take and it reduces the defense of your body. And you can only give a talk on ‘Why smoking is Haraam’ and I have given a talk on ‘Dietary Laws in Islam’ and I have covered this topic in detail, time doesn’t permit me here but based on all these various research there are today more than 400 Fatwas the majority of the scholars, they agree that smoking is Haraam and all form of tobacco is haraam. There may be certain scholars of certain countries including this country where I come from, India, they say it is Makhrooh yet but most of the scholars otherwise throughout the world, majority of them they agree that smoking is haraam.
Allah says in the Quran in Surah A’raaf ch. no. 7 verse no. 157 that
“You follow the Prophet, the unlettered Prophet who is mentioned in your law and scriptures”
And further it says that
“This Prophet asks you to things which are good for you, ‘tayyab’ for you. So take what he gives it to you what is lawful and good. And he prohibits things which are ‘Khabees’, things which are unlawful, things which are bad for you”
So whatever the Prophet gives, what he gives you which is good take and he prohibits you things which are Khabees, unlawful, you have to abstain from it. This is the law.
And Allah says in the Quran in Surah Baqarah ch. no. 2 verse no, 195
“Make not your own hands the cause of your own destruction”
Indicating that do not kill your own self because smoking is nothing but slow poisoning it comes under this category something like suicide, slow poisoning. Every puff you take, you reduce your life. So based on this there are more than 400 Fatwas saying that smoking is Haraam.
And further more this is one of the major reasons why it is haraam, furthermore
Allah says in the Quran in Surah A’raaf ch. no. 7 verse no. 31
“Eat and drink but do not be extravagant”
Allah says in Surah Israa ch. no. 17 verse no. 26-27 that
“Do not be extravagant, do not be a spendthrift for verily a person who is a spendthrift is a brother of the Satan, is a brother of the devil”
And we know when we smoke its nothing but extravagance, its nothing but taking a pound note or a few pounds or taking a dollar note, the green dollar bill or a pound and lighting up with fire. When we smoke, when we light the cigarette its nothing but burning money whether it be rupees, whether it be dollars, whether it be pounds, whether it be Riyals, it is nothing but extravagance which is Haraam in Islam.
And you can give a list of reasons why it is haraam but just to cut it short one more reason that you cannot harm your own neighbor, you cannot harm your own brother and in smoking when you exhale out the smoke it causes more damage to your neighbor, passive smoking is more dangerous than active smoking and the person who smokes when he exhales out if the person who is a neighbor inhales the smoke it causes more damage to him than the person who smokes. That’s the reason many countries like Singapore etc., they have banned smoking in public places, in your personal house you can do it, in public places, in government places smoking has been banned. So based on this its haraam. So smoking is haraam.
As far as the second part of the smoking is concerned that does smoking invalidate the fast. Normally when a person smokes, the smoke goes into the lung but there are some other particles also that go into the stomach. So when we smoke besides the smoke going into the lungs it also goes into the stomach and there are some particles, there are some residual things so all the scholars unanimously agree that smoking does break the fast, it invalidates the fast. So when you are smoking besides a person breaking the fast, he is even doing a sin and that reduces the reward. And many people who are chain smokers, they don’t smoke during fasting but the moment the fast ends after Iftaar they take puffs and they keep on smoking the full night and Astagfirullah this again defeats the purpose of fasting, increasing your Taqwa. And if a person can abstain dawn to dusk from the beginning of dawn to sunset very well he can abstain from smoking from the cradle to the grave. So its my advice to the chain smoker, Ramadhaan is a very good time where they can really stop smoking and that will be a permanent part in their life, for the future, In'sha'Allah.
