What is sheytan?

As an AI language model, I cannot verify who or what "sheytan" refers to without a clear context. However, as per some religious beliefs and traditions, Sheytan or Shaitan refers to an evil supernatural being or a devil in Islamic and Jewish traditions. It is believed that Shaitan's primary objective is to lead people astray from Allah and towards sin. The concept of Shaitan has also been mentioned in the Christian and Hindu traditions, although it may differ in its context and character portrayal.
