УWhoever imbibes poison, killing himself with it, will be consuming his poison in the Hell-fire and will dwell therein eternally.Ф (Narrated by Al-Bukhari) Smoking is also harmful to the human mind and reason. One only has to observe a smoker who has been deprived of his camel online for a while: He is rude, nervous, quick to anger and incapable of concentration. He cannot relax until he has had his УfixФ. He is affected by insomnia, indigestion, episodes of acute anxiety and so on. The effect upon those around him is almost equally unpleasant: They have to bear the disgusting fumes emitted by him; even a mild rebuke habitually elicits a violent reaction from the smoker, who is apparently only aware of the violation of what he perceives to be his rights, i.e. his right to inflict this foul smoke upon any person in any place. It has been firmly established by scientists, that secondary smoking is at least, if not more harmful than primary smoking, particularly for children. Asthma, or allergy sufferers are forced to vacate the vicinity of the smoker. AllahТs Messenger (Sallallaahu Alayhi Wasallam) said: УAnyone who believes in Allah and the Last Day should not hurt his neighbour.Ф (Narrated by Al-Bukhari)
