The film tells the story of Hz. Ömer, who strove to establish justice throughout his caliphate. During the years when Islam was spreading in Mecca, the pagan Quraish tribe still worshipped idols. The leader of the tribe, Abu Jahl, saw Islam as a threat to his own beliefs. Abu Jahl decides to have Muhammad killed in order to prevent the spread of Islam. He assigns Umar, the son of Hattab, to carry out this task. However, while Umar is preparing to kill Muhammad, he learns that his brother and brother-in-law have become Muslims. Upon reading the Quran, Umar also converts to Islam shortly thereafter. He begins to fight against Abu Jahl and the Quraysh tribe. After the death of the Prophet Muhammad, Umar, who became the caliph, will strive to establish justice in the country's administration.
