Like Eid al-Fitr, Eid al-Adha starts with a Sunnah supplication to God of two rakats emulated by a sermon (khutbah). Eid al-Adha festivals begin after the plunge of the Hujjaj from Mount Arafat, a slope east of Mecca. Eid reparation may occur until nightfall on the thirteenth day of Dhu al-Hijjah. The times of Eid have been singled out in the Hadith as “days of recognition”. The takbir of Tashriq are from the Fajr request to God of the ninth of Dhul Hijjah up to the Asr supplication to God of the thirteenth of Dhul Hijjah (5 days and 4 nights). This equivalents 23 petitions to God: 5 on the 9th–12th, which approaches 20, and 3 on the thirteen.
