Ghadir's Weather: Was the Weather Hot in Ghadir?

The present paper is a review and analysis of a doubt regarding Ghadir that has been recently published in cyberspace in the form of papers, questions and comments entitled “was the weather warm in Ghadir?" In this doubt, expressing that the Ghadir event coincided with March and a hot weather is unlikely and even impossible in this season, it is claimed that the Shiite argument for the appointment of Ali (As) as the successor to the prophet is senseless. Using a historical and climatic analysis of Ghadir and the library-based and analytical method, the paper responds to this question by proving that the evidence for the definite Imamate of Ali (As) is not limited to Ghadir hadith and the implication of the word "Mola" in the Hadith of Ghadir to the authoritative Wilayat of Ali (As) cannot be rejected by the heat of that day. In that geographical region, hot weather in winter is scientifically, rationally or normally likely. According to Sunni traditions, in the day of Ghadir event, the weather was extremely hot and denying hot weather means refuting the authenticity of traditions, and is therefore ineffective the issue of Ghadir.
