Question: What is the Islaamic ruling regarding farming tobacco and the money earned by the farmers from selling it?
Response: It is not permissible to farm tobacco, or to sell it and nor to smoke it because it is haraam in many ways: due to its harmful effects on [one’s] health, due to its evilness and lack of benefit. [So] it is upon the Muslim to leave it [completely] and distance himself from it, not to farm it or trade in it because if Allaah has made something haraam then it’s trade is also haraam.
And Allaah [alone] has the Complete knowledge [of all affairs].
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
