Abū Muḥammad al-Ḥasan b Mūsā an-Nawbakhtī (الحسن بن موسى النوبختي; born late 9th century and died between 912 and 922) was a Persian and leading Shī'ī theologian and philosopher in the first half of the 10th century.^[1][2][3] The Nawbakhtī family boasted a number of scholars famous at the Abbāsid court of Hārūn al-Rashīd. Al-Ḥasan ibn Mūsa is best known for his book about the Shi'a sects titled Firaq al-Shi'a.
