Abd al-Ahad

ʻAbd al-Aḥad (ALA-LC romanization of عبد الأحد) is an Arabic male given name. It is built from the Arabic words ʻabd and al-Aḥad, one of the names of God in Islam. It is listed in the Qur'an, which give rise to the Muslim theophoric names. It means "servant of the only One". Abd al-Ahad is also common among Arabic-speaking Christians, particularly Syriac Orthodox and Syriac Catholics -- several of whose clergymen, including the late patriarch Ignatius Peter VIII Abdul-Ahad, have borne the name.
