Hidayat Allah was the son of Qūsṭanṭīn, son of Yūḥannā and Hissin. Through his father, Yūḥannā, son of Nūr al-Dīn and Muglah, Hidayat Allah was the nephew of the patriarchs
Ignatius Ni'matallah () and Ignatius David II Shah (). Hidayat Allah's paternal grandfather Nūr al-Dīn, son of Šay Allāh and Maryam, was a brother of the patriarch
Ignatius John XIV () Hidayat Allah's father's family had moved from
Bartella, near
Mosul, to
Mardin in the mid-fourteenth century and were descended from the priest Abū al-Karam, who lived in the thirteenth or fourteenth centuries. From 1591, he opposed the patriarch
Ignatius Pilate with the support of his uncle Timothy Tuma until they were reconciled by John Wanki in 1593. Hidayat Allah became patriarch of Antioch in 1597 or 1598 and assumed the name Ignatius. In 1611, he visited the
Monastery of Saint Mark at
Jerusalem with Maphrian Elia, Bishop Michael Al-Kakari, and Bishop Yacoub Al-Ksorani. As they returned from Jerusalem, where they had consecrated the
Chrism, they also visited the village of
Sadad in Syria in 1614 (

Homs and ordained two priests. Hidayat Allah consecrated the Chrism at
Aleppo in 1625 (

bishop of Edessa, Qūrīllūs, bishop of the
Monastery of Mar Ilyan, and Diyūsqūrūs, bishop of the
