Signifance of this Dua

Eid-E-Zehra or Eid-E-Shuja Celebration (Eid-E-Zahra):
Eid-E-ZehraThe extraordinary two-month period of Azadari (mourning) reaches its climax with the death of our 11th Imam, Imam Hassan Askari (as) on the 8th of Rabi al-Awwal. The day that follows, according to tradition, is the greatest Eid (celebration) for the lovers of the Ahlul Bayt (as). Known as Eid-E-Zehra, this day honours the daughter of Prophet Muhammad (peace be upon him and his family) as a day of great joy and happiness for the believers.
As we recall, this past 70-day period has seen the commemoration of the martyrdom of no less than six infallible – Holy Prophet Muhammad, Imam Hassan, Imam Hussain, Imam Sajjad, Imam Raza and Imam Askari (peace be upon all of them). In addition, we also have marked the death of other personalities such as Hazrat Abbas, Bibi Masuma-E-Qum (Masooma-E-Qum) and the companions and friends of the Imam Hussain (as) on the plains of Karbala (Kerbala). Finally, after such a period of sorrow, we remove the black from our place of worship and bodies, and go forth to implement the lessons learned during these last months.
One of the important things that we mark is the first official day of the leadership of our living Imam, al-Hujjat ibn Hassan al-Askari [may Allah (SWT) hasten his return]. As narrated in our Duas, Ziyaraat and traditions, the return of our 12th Imam will mark the revenge of the blood spilled in Karbala.
It is with this important event that we celebrate Eid-E-Zahra and sincerely ask Allah (SWT) to hasten the return of His final proof. Through the justice that the Imam will show, this day will truly be marked as the day of Eid for Fatima al-Zahra (sa) and all her true followers
