Project Cigarette: Reasons cigarette smoking is Haram

Praise be to Allah, the Lord of the Worlds; and Blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. 

  1. Smoking is Haram (prohibited) due to its many harmful effects and bad consequences. This is a well-known generally accepted fact. No one could doubt or refute this truth. 
  2. Harms of smoking have been proved through evidence that doctors have agreed upon. 
  3. Tobacco used for smoking is bad whereas Almighty Allah made lawful for his slaves all the good and useful and forbade what is bad and harmful. Allah says (Interpretation of meaning): {They ask you (O! Muhammad) what is lawful for them (as food) say: lawful unto you are At-Tayibat (foods which Allah made lawful )}. [5:4]. 
  4. Almighty Allah Say' stating the purpose for which He has sent the Prophet: {He allows them which is lawful (At-Tayibat) and prohibits them which is unlawful (Al-Khabaith).

    In brief the smoking is a means of killing oneself slowly and Almighty Allah has forbidden killing oneself. So no one should differ in its prohibition. Allah knows best.
