Religion is an integral element of every society and culture.

It plays a crucial role in providing a person with a cultural identity. It also helps in protecting the heritage and diversity of a country.

Faith also helps build values like love, empathy, respect, and harmony. It helps create an ethical framework and regulates matters in our daily lives, which helps in the character building of a person.

Moreover, religion plays a crucial role in establishing our connection to the divine and developing the belief that supreme energy is above everyone, which regulates our daily actions and teaches us morality and virtue.

Religion serves different functions in different people's lives, and significant differences in religious beliefs and practices exist.

It is estimated that the majority of the Iranian population identifies as Muslims. Most Muslims are Shi'a (also known as Shi'ite) Muslims, and around 5-10% of the population identify as Sunni Muslims.

Shi'a Islam in Iran


Islam is the faith of 98% of Iranians, of which roughly 89% are Shi'a. Within Shi'a Islam, there are various sects. The most significant is the Twelver Shi'a sect. The next largest Shi'a group is the Nizari Ismailism Shi'a, sometimes called Seveners.

The titles Twelver’s and Seveners are derived from their belief in how many divinely decreed leaders were descendants of the Islamic prophet Muhammad(S.A.W.A.) through his daughter Fatimah(A.S.) and his son-in-law 'Alī (A.S.).

The Shia Imams are considered infallible and the best source of knowledge about the Qur'an and Islam. They are believed to be the most trusted carriers and protectors of prophet Muḥammad's usual practice and the worthiest of emulation.

Among all these Imams, only Imam Ali ar-Ridha (765 – 818 AD) is buried in Iran at the Imam Reza shrine. The predominant school of faith, practice, and jurisprudence (Madh'hab) in Shi'a Islam is Jafari, established by Imam Ja'far as-Sadiq (A.S).
