Islam grants total intellectual freedom and stresses the principle of freedom. It strictly forbids people being forced to adopt a certain creed or religion. The freedoms granted in Islam include freedom of belief, thought, speech, and the freedom to criticize. This principle of freedom in Islam was revealed directly and did not develop gradually over time. Freedom of expression is guaranteed in Islam except it does not include freedom of insult, defamation, or slander, and religion, honor, and dignity should not be disrespected.
