A group of experts on Sihah and Musnads from Ahl al-Sunnah and their collections on hadiths have narrated in numerous and precise ways, exceeding the boundary of successive transmission that: "When returning from the "Farewell Pilgrimage", the holy Prophet (s.a.w.a.) halted at a place called "Ghadir Khum" and delivered a sermon, advising the Muslims to get hold of two precious treasures (i.e., the Book of Allah and the Prophet's household), adding that the two would never be separated from each other until they joined the holy Prophet (s.a.w.a.) near the pond of Kauthar.

The writer's opinion : The hadiths of "Ghadir", "Wilayah", "Saqalain", "Manzilat", "A’imma Ithna-Ashar", "Tair", "Kisa", "Mubahila" and other such hadiths are all among the most famous hadiths with the most authentic chain of transmitters and with abundant channels. They have been narrated by a group of the Prophet's companions and no one is able to find among the narrations any hadith that can be measured with the afore-mentioned hadiths in terms of credibility, successive transmission and fame except very little. Also, recording the entire chain of transmitters and texts of these narrations are incredibly difficult such that there are monographs available for them, and sometimes a few of them make up several volumes which as a token of blessing and good luck, we shall list in the index of this book.

It is God’s special Grace that made us partisans to the guardianship of the Commander of the Faithful and the Imams from his children to the Imam of the Age, Hazrat Mahdi (a.t.f.s.)
