it was recently published by kitabak. gholamreza heidari abhari is the author of this book. in the last years of his life, with his blessing, the prophet, peace and blessings of god be upon him, always took steps to identify hazrat ali (peace be upon him) as his successor. the story of ghadir khoon is just one of those stories, and perhaps we can say that it is the peak of the prophet's effort to introduce him, peace be upon him, as his successor. they say: god, whoever loves him, love him , and whoever is enmity with him, make him an enemy. one of the authentic hadiths in shia books.
