The paper examined the impacts of social media in influencing public opinion in Muslim communities. Invariably, public opinion is a vital tool for government, politicians, and decision-makers in all communities, including Muslims’. Social media is a powerful and strong machine to mold, shape, and influence public opinion. In developing this paper data were obtained from a secondary source, meaning data were generated from several documentaries such as- books, journals, newspapers, magazines, archives, etc. From the available literature, the study found that the mass media in general, and the social media in particular, are very important in making and influencing public opinion in the society, especially the Muslim communities. To explain the topic under study the researchers adopted two theories; culturists and Classdominant Theories. The theories claim that people interact with media to create their own meanings out of the images and messages they receive. This theory sees audiences as playing an active rather than a passive role in relation to social media. In addition, the assumption of these theories is that social media replicates and plans the view of a marginal elite, which controls the system to influence people's opinions. The researcher recommended that politicians, governments, and policymakers should pay much attention to social media and to use them wisely in a positive way, for their own good and for the benefit of their communities in particular and the society at large.
