What is the meaning behind the Hadith mentioned in Bihar al-Anwar, Vol. 98, Ch. 14, Hadith 11, that says visiting Imam Husain's grave is equivalent to visiting Allah on His Arsh?
The Arsh is The Knowledge which is carried by eight most humble servants of Allah; Noah, Ebraheem, Musa, Easa, Muhammad, Ali, Hasan and Husain. The eight who carry the Arsh (Knowdge) are mentioned in Quran, Sura 69, verse 17 and explained in authentic narration from Muhammad ibn Muslim from Imam Al-Baqir (AS) in Kanz Al-Fawaa'id quoted by Biharul Anwaar V.24, P. 90 and V.55, P.35 and in Tafseer Al-Borhani , V. 4 , P. 377.
Visiting the shrine of Imam Husain (AS) is like visiting the Arsh of Allah (Eight greatest servants of Allah who carry the Arsh).
This shows the great importance of visiting Imam Husain (AS).
Wassalam.
