Introduction: Islam is the religion that provides a comprehensive code of life including social and personal spheres. Islam has been the target of many stereotypes, including extremism, for several decades. The reason behind these stereotypes is based on certain facts and, to some extent, is widely propagated by the media. Many people involved in criminal activities are easily highlighted by the media and attract public attention if they are Muslim. The consequences of the September 11 attacks play a major role behind these stereotypes. Muslims face stigma and other forms of racial discrimination. They face strict security measures at international airports. Employers have also shown concern or hesitation when hiring Muslims, particularly immigrants. Besides the September 11 attacks, there are many reasons why Muslims have been stigmatized in the United States for many decades. Background Muslims have faced propaganda from the Western world media for many decades. Western media are very quick to publicize any negative incident in which Muslims are involved.

One of the major events that gave rise to such stigma was the September 11 attacks on America.

Although abnormal, normally Muslim students are labeled terrorists and are often verbally coerced and mocked to return to their home countries. The general conclusion can be drawn from the study that the United States suffered a lot during the September 11 attacks, but those who are still facing the consequences of this incident are Muslims around the world and especially those present in the United States. -United. Various reasons other than the 9/11 attacks behind the stigmatization of Muslims worldwide include stereotypes against Muslims in terms of lack of flexibility, unusual culture, simple lifestyle and aggressive behavior..
