This paper attempts to examine Bayazid's thoughts according to his shathiyat1 and research in Sufi and mystical people and clear-sighted persons who are highlighted in Islamic mysticism history about foregoing subject In the first meeting of the sunlight of Tabriz (Shams-e-Tabrizi) and young teacher of Balkh (Mowlavi) in Quniyeh. A question caused commotion in Mowlavi's thought. This question has two halves, one half is a Shateh like Bayazid Bastami. In this question Shams Tabriz asked Mowlavi: "Who is superior, prophet or Bayazid ?If prophet is superior and of course he is superior, why Bayazid has said: I am pure and what a superior position I have and prophet has said: I haven't known you, in proper condition. These two halves question have two predicates that second predicate is legal, famous and acceptable, but the first predicate is shath like statement that involves every knowledgeable mind. Reaction of Bayazib's speech causes support of religious dignitaries such as: Imam Ismael Mostamali Bakhari, Imam mohammad Kalabazi, Atar and movlavi ,….And colludes suitable analysis by religious dignitaries (sheikh) such as Abnaeim Isfahani ,Abu nasr Seraj and Khajeh Qosheiri. Whatever is considerable in Bayazid's shath can be classified in four chapters: his narrow-mindedness, shaths and his harsh speech, Bayazid's knowledge, that is simulating madness and God's love in Bayazid's heart.
