The first Eid al-Adha in Islam
The Prophet ﷺ led the Muslims in the first Eid al-Adha prayer in Madinah and sacrificed two horned white rams which he slaughtered with his own hand, reviving the way of Ibrahim — a Sunnah that endures in the Ummah until the Day of Resurrection.
In the second year of the Hijra the two Eid prayers and the sacrifice were legislated. He ﷺ went out on the day of Nahr to the prayer-ground, led the people in two rakʿas, then addressed them and ordered whoever had not slaughtered to slaughter after the prayer, saying: "Whoever slaughters before the prayer, it is only meat he has offered to his family."
He ﷺ sacrificed two horned white rams, slaughtering them with his noble hand, naming Allah and saying the takbir and placing his foot on their sides, as Anas narrated in the two Sahihs — reviving the Sunnah of his father Ibrahim when Allah ransomed his son Ismaʿil with a great sacrifice.
The Day of Nahr became the most sacred day of the year; he ﷺ named it "the day of the Greatest Hajj." On it two rites join for the Muslims — the Eid prayer and the sacrifice — and for the pilgrims of Allah's House there join in it the stoning of the pillar, the sacrifice, the shaving and the tawaf.
