IntroductionCommunication today is increasingly seen as a process through whichthe exchange and sharing of meaning is made possible. Commtinication asa subject of scientific inquiry is not unique to the field of mass communication.Mathematicians, engineers, sociologists, psychologists, political scientists,anthropologists, and speech communicators have been taking an interest inthe study of communication. This is not surprising because communicationis the basic social process of human beings. Although communication hasgrown into a well developed field of study, Muslim scholars have rdrely hcusedon the study of communication. Thus, a brief introduction to the widely usedcommunication concepts and a framework for the study of communicationwithin the context of this paper is provided.In 1909, Charles Cooley defined communication from a sociologicalperspective as:The mechanism through which human relations exist and develop -all the symbols of mind, together with the means of conveyingthem through space and preserving them in time. It includes theexpression of the face, attitude and gesture, the tones of the voice,words, writing, printing, railways, telegraph, and whatever elsemay be the latest achievement in the conquest of space and time.In 1949, two engineers, Claude Shannon and Warren Weaver, definedcommunication in a broader sense to include all procedures:By which one mind may affect another. This, of course, involvesnot only written and oral speeches, but also music, the pictorialarts, the theater, the ballet, and, in kct, all human behavior.Harold Lasswell, a political scientist, defines communication simply as:A convenient way to describe the act of communication is to answerthe following question: Who, says what, in which channel, towhom, with what effect?S.S. Stevens, a behavioral psychologist, defines the act of communication as:Communication occurs when some environmental disturbance (thestimulus) impinges on an organism and the organism doessomething about it (makes a discriminatory response) . . . Themessage that gets no response is not a commnication.Social psychologist Theodore Newcomb assumes that:In any communication situation, at least two persons will becommunicating about a common object or topic. A major functionof communication is to enable them to maintain simultaneousorientation toward one another and toward the common object ofcommunication.Wilbur Schramm, a pioneer in American mass communication research,provides this definition:When we communicate we are trying to share information, anidea, or an attitude. Communication always requires threeelements-the source, the message, and the destination (thereceiver).
