The history of Iranians' interest in Islam and the Ahl al-Bayt of the Holy Prophet of Islam (AS) reaches the beginning of Islam, and even today, Islamic Iran is known for the love and following of the infallible Imams (AS). Some people try to cast doubt on this issue by insisting on some unreliable traditions and distorting religious texts. In this research, a hadith attributed to Imam Hussein (a.s.) has been investigated, in which the Iranians are introduced as the enemy of the Ahl al-Bayt (peace be upon them). Using library sources and descriptive methods, the mentioned hadith and other similar hadiths have been investigated. It was found that it is not authentic from the point of view of a document and cannot be attributed. Another thing is that assuming the authenticity of the reference, this hadith has been distorted a lot. Thirdly, a non-expert translation of that hadith has been presented in such a way that its meaning is distorted. Fourthly, even assuming the correctness of the citation and translation, as well as the absence of distortion in the text of this hadith, the contrary hadiths have not been paid attention to. While there are many other hadiths praising and honoring Iranians.
