Islamic Human Rights Day is observed in Iran every August 5, commemorating the adoption of the Cairo Declaration on Human Rights in Islam by the Organization of Islamic Cooperation (OIC). This declaration, adopted on August 5, 1990, serves as a response to the Universal Declaration of Human Rights, aiming to align human rights with Islamic values. The OIC, which has 57 member states, was established in 1969 to promote cooperation in various fields while preserving Islamic principles. The Cairo Declaration guarantees rights similar to those in the Universal Declaration but emphasizes sharia as the sole source of human rights in Islam, which has led to criticisms regarding gender equality and religious freedom. In Iran, the anniversary of this declaration is marked as Islamic Human Rights Day, reflecting the country's engagement with these specific interpretations of human rights.
