Hadith.2278 - Imam Jafar ibn Muhammad Al-Sadiq (as) was asked about who the "sacrificed one" (Dhabih) was, and Imam (as) said:
"Isma'il (as), because Allah (swt), the Mighty and Majestic, mentioned his story in His Book and then said: 'And We gave him glad tidings of Ishaq, a prophet from among the righteous.'" (Surah As-Saffat 37:112)
