Eid-e-Ghadir is an annual religious holiday celebrated by Shia Muslims, occurring on the 18th day of the Islamic month of Dhul Hijjah. This holiday commemorates the appointment of Ali ibn Abi Talib as the leader and religious authority after Prophet Muhammad, which is believed to have been announced at Ghadir Khumm during the Prophet's return from Mecca to Medina. The event is marked by gatherings where Shia Muslims exchange gifts and partake in festive meals. Celebrations often include communal feasts and acts of giving, emphasizing love and generosity among friends and family. The holiday is particularly significant in countries with large Shia populations, such as Iran, Iraq, and Lebanon.
