This article develops the concept of fitnah and its bearing on freedom of expression. It puts together information from the unconsolidated source materials of the Shari'ah in a manner reflecting the interest and style of a modern student of comparative law. It also develops the theme that modern interpretations of seditious speech and conduct have done much to restrict the scope and substance of the freedom of expression. The Shari’ah tends to advocate the opposite, as it confines the scope of restrictions to measures necessary to repel an imminent danger to normal order in society. The individual's freedom to investigate facts and ideas and to formulate and express an opinion are integral to Islam's approach to the dignity of the individual and the quest for ascertaining the truth.
