Saint Maruf was the bishop of the city of Tikrit, renowned for his learning and piety. He wrote about the martyrs who suffered for the Christian faith and left works in the Syriac language, among which are "Commentary on the Gospel", "Songs of Maruf", "Liturgy of Maruf", and "73 Rules of the Universal Nicaean Council".
In 381, he participated in the II Universal Council of Constantinople against the heresy of Macedonius, and in 383, at the Antiochian Council against the Messalians.
In 403–404, he went to Constantinople to intercede for the Persian Christians. He was sent twice by Emperor Theodosius the Younger to Shah Izdegerd to negotiate peace between the empire and Persia.
In 414, as an envoy at the court of Izdegerd, he contributed to the freedom of Christian confession in Persia, restored churches, and transferred the relics of the holy martyrs to Martiropolis. He died around 422. The relics of Saint Maruf were later transferred to Egypt and laid in the Skete Monastery of the Mother of God.
