Abu al-Qasim al-Husayn ibn Ruh al-Nawbakhti


Abu al-Qasim al-Husayn ibn Ruh Nawbakhti (Arabic: أَبُو ٱلْقَاسِم ٱلْحُسَيْن ٱبْن رُوح ٱلنَّوْبَخْتِيّ, ʾAbū al-Qāsim al-Ḥusayn ibn Rūḥ an-Nawbakhtīy) was the third of the Four Deputies, who are believed by the Twelvers to have successively represented their Hidden Imam, Muhammad al-Mahdi, during his Minor Occultation (874–941 CE). Ibn Ruh in this role succeeded Abu Ja'far Muhammad ibn Uthman in 917 CE. After some twenty years in office, Ibn Run died in 937 CE and was succeeded by Abul Hasan Ali ibn Muhammad al-Samarri, the fourth and final deputy.
