The eternity of Ghadir event

The Wise God has willed the Ghadir historical event to remain in all ages and centuries, as a live history, attracting the hearts and minds, and the Islamic writers to discuss it in the commentary, history, tradition and theology books, and the religious orators to deliver lectures about it, and call it one of the undeniable virtues of Imam Ali (a.s.).
Not only the orators and lecturers, but also the poets too have been suggested by this event, and have lighted their literary talent through thinking and reflection on it, as well as increasing their loyalty to the owner of guardianship. They have left the best poems in different forms and various languages. (The Late Allameh Amini has mentioned an important part of Ghadir poems in every century of the Islamic history, while describing the attributes of the poets in the eleven volumes of Al-Ghadir book narrated from popular Islamic resources).
In other words, no other historical event in the world, has been noted so much by different classes, including traditionist, commentator, theologian, philosopher, orator, poet, historian and biographer.
One of the reasons for eternity of this tradition, is revelation of two Quranic verses (1) in respect to this event, and since Quran is eternal and everlasting, this historical event too will be never forgotten.
It is noteworthy that referring to the history clarifies that eighteenth of Zelhejjah has been known among Moslems as the Eid Ghadir, so that Ebne Khalkan says about Mostalli Ebne Mostansar: The people paid homage to him on eighteenth of Zelhejjah, Eid Ghadir, 487 A.H. (2), and he writes about Mostansar Bellah Abidi: He passed away twelve nights before the end of Zelhejjah, 487 A.H. It is the same night of eighteenth of Zelhejjah, the night of Eid Ghadir. (3)
It is interesting that Aboureyhan Birouni, in Assarol Baqieh, has called Eid Ghadir one of the feasts, which all Moslems celebrated it. (4)
Not only Ebne Khalkan and Aboureyhan Birouni have called it an Eid, but also Thalebi, one of the other famous Sunnite scholars has called Ghadir one of the popular nights among the Islamic nation. (5)
This Islamic Eid dates back to the time of Prophet (s.a.w.a.), because on that day, the Prophet (s.a.w.a.) instructed the immigrants and helpers, and rather his wives, to go to Ali (a.s.) and congratulate to him for guardianship and Imamate.
Zeid Ebne Arqam says: Aboubakr, Omar, Osman, Talhe and Zobair from among the immigrants were the first who paid homage to Ali (a.s.), but the congratulation and paying homage ceremonies was continued till sunset. (6)
