Al-Milal wa al-Nihal
Kitāb al–Milal wa al-Nihal, written by the Islamic scholar Muhammad al-Shahrastani, is a non-polemical study of religious communities and philosophies that had existed up to his time, considered to be the first systematic study of religion. It was written around 1127-1128 and divides religions between sects, which have written doctrines, and creeds which do not.
A French translation of the book by Gimaret, Monnot and Jolivet was sponsored by UNESCO.
