Question: Is smoking cigarette and weed unlawful in Islam?
Smoking cigarette is not a sin, but it can be considered as a disliked act according to this verse:
“Spend your wealth in the way of Allah and do not put yourselves in jeopardy with your own hands. Do all things gracefully, for Allah likes those who do all things with excellence.” (2:195)
Smoking weed is unlawful. Allah the Almighty says:
“Oh you who believe! Intoxicants, gambling, idols, arrows for seeking the future or luck are all abominations, the works of the strayed. So, keep away from them that you may attain the true success. The strayed ones only desire to create grudge and hostility between you with intoxicants and gambling; and hinder you from the remembrance of Allah (Quran) and the prayers. Will you, now, desist?” (5:90-91)
All kinds of narcotics and liquor are considered as intoxicants. (see also. 2:219)
