The verse of holy Koran "verily the most honored of you in the sight of Allah is [he who is] the most virtuous of you" directly shows that in god's willing there is no superiority of a man or a group than others except those who have piety to god. In fact, the Islamic identity focuses on the superiority of piety among humans and does not focus on superiority of a man or a group that causes Islamic identity theoretically be against other competitive identities such as ethnic, global and national identity. Therefore, this research aims to study the relationship between Islamic identity and competitive identities (ethnic, national and global). In this way based on Sheldon Stryker theory and survey method, 431 students have elected and have analyzed. The results have shown that there was positive significant relationship between Islamic identity, national and ethnic identity, and negative significant relationship between Islamic identity and global identity. In addition, multivariate regression results have shown that the variables national and global identities have explained 45 percent of the variation of Islamic identity variable. The results shows that national and ethnic identity amplify the Islamic identity and they have positive relationship with it and in fact they are not a competitive identity for Islamic identity but global identity has negative relationship with Islamic identity and therefore it is a competitive identity for Islamic identity.
