Most Turkish people are Muslim, and the majority follow Sunni Islam. However, there are also significant minority populations of Alevis, Shi'a Muslims, and non-Muslim religious communities in Turkey, such as Christians and Jews.

In general, Turkish people believe in the existence of one God and the importance of following the teachings of the prophet Muhammad. 

They also believe in the importance of performing good deeds, upholding ethical and moral values, and adhering to the principles of Islam as outlined in the Qur'an. Many Turkish people also follow the Five Pillars of Islam, which include the declaration of faith, prayer, charity, fasting during Ramadan, and pilgrimage to Mecca.

In addition to religious beliefs, Turkish culture is influenced by various cultural and historical traditions, such as the Ottoman Empire, which significantly impacted the country's art, music, literature, and architecture.
