 The reported juristic disagreement among Muslim scholars on the ruling concerning smoking, since its appearance and spread, is not usually based on differences between legal proofs, but on the difference in the verification of the cause on which the ruling is based.They all agree that whatever is proved to be harmful to the body and mind is prohibited, yet they differ whether this ruling applies to smoking.Some of them claimed that smoking has some benefits, others assured that it had few disadvantages compared to its benefits, whereas a third group maintained that it had neither benefits nor bad effects.
