Hadith.2279 - Imam Jafar ibn Muhammad Al-Sadiq (as) was asked: "Where did Ibrahim (as) intend to sacrifice his son?" Imam (as) said: "At the middle Jamrah. When Prophet Ibrahim (as) intended to sacrifice his son, Archangel Jibril (as) turned the knife over, pulled the ram from Mount Thabir, pulled the boy out from underneath, and placed the ram in the boy's place. Then a call came from the left side of the Mosque of Khayf: 'O Ibrahim, you have fulfilled the vision. Indeed, We thus reward the doers of good. This was indeed a manifest trial. And We ransomed him with a great sacrifice.' It was a ram, piebald, walking in black, grazing in black, looking in black, defecating in black, urinating in black, horned, and strong. It had grazed in the meadows of Paradise for forty years."
