Radicalism is an ideological movement and political approach that is foreign to Islam. When radical groups are examined, it gradually becomes clear that they are, in reality, using a compilation of communist slogans and methods or that they have adopted the "fanatical rage of the Time of Ignorance" (Qur'an, 48:26). One of the common characteristics of such ideologies is their emotional force, an underlying cause of radicalism that is totally incompatible with God's commands. The Qur'an describes Muslims as people who control their anger and who are reasonable, moderate, and tolerant. Muslims must be polite and respectful when interacting with people of different beliefs and ideologies.
