Celebrating ‚Eid-e-Zehara The extraordinary two-month period of mourning reaches its climax with the death of the 11th Imam on the 8th of Rabi ul-Awwal. The day that follows, according to tradition, is the greatest Eid (celebration) for the lovers of the Ahlul Bait. Known as ‚ÄòId-uz-Zahra, 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.
