The History of Shiite Notion's Entrance into the Quatrains Ascribed to Abu Said Abulkheir and Others

It is said that the first Persian mystical poems must have been composed before the fifth century. This matter can be traced via a number of signs extant in the old texts. Though the original form of such poems have not been recorded in the books، one of the great poets of Samanid and Qaznavi periods who has a special share in circulating mystical notions in poetry is Abu Said Abulkheir. There are a few verses of the mystical poems ascribed to him in the late manuscripts whose analysis can give us an image of how and when some Shiite notions gained currency in Persian quatrains. Analyzing the quatrains ascribed to Abu Said، this research aims to explore their status and، while answering the probable questions، the entrance of such notions into mysticism is also recognized.
