Manichaean scripture
The Shabuhragan is a special book in Manichaeism that was written by the founder, Mani. It was made for King Shapur I of Persia and was written in Middle Persian. The book explains Mani's religion, which combined ideas from Zoroastrianism, Christianity, and Buddhism. This is the only book that Mani wrote in Middle Persian, instead of Syriac. The book is listed as one of the seven important books of Manichaeism in Arabic history, but it is not one of the seven listed in the Manichaean religion itself.
