Eid al-Ghadir
Eid al-Ghadir (Arabic: عید الغدیر, romanized: ʿīd al-ghadīr, lit. 'feast of the pond') is a commemorative holiday, and is considered to be among the most significant holidays of Shi'ite Muslims and Alawites.[2] The Eid is held on 18 Dhul-Hijjah at the time when the Islamic prophet Muhammad—according to interpretation in Syiah—appointed Ali ibn Abi Talib as his successor. According to Shia hadiths, this Eid has been named "Eid-e Bozorg-e Elāhi" (Persian: عید بزرگ الهی; i.e. the greatest divine Eid),[3] "Eid Ahl al-Bayt Muhammad"[4][5] and Ashraf al-A'yaad (i.e. the supreme Eid).[6][7]
