What is the opinion of His Eminence (may Allah prolong his life) regarding the multiple narrations of Lady…

Answer

In the name of Allah, concerning hiding the grave, it appears from the traditions that it was hidden by Ali ibn abi Talib (PBUH) as protection to the grave from the attacks of those who oppressed her (PBUH). For the multiple narrations of her martyrdom day, the reason was not known. Perhaps, Allah wants the only daughter of the prophet who was oppressed to be remembered more than once as a commemoration for her and spreading her oppressiveness. Allah is the All-Guide and He knows best.
