Jami' at-Tirmidhi — Hadith #27116

Ibn Abi Umar narrated to us, Sufyan bin Uyaynah narrated to us, on the authority of Abu Ishaq, on the authority of Al-Harith, on the authority of Ali, who said: The greatest day of Hajj is the day of sacrifice. Abu Issa said, but he did not narrate it. This is more authentic than the first hadith, and the authenticated narration of Ibn Uyaynah is more authentic than the narration of Muhammad ibn Ishaq is traced back to the Prophet. This is how more than one of the huffaz narrated on the authority of Abu Ishaq, on the authority of Al-Harith, on the authority of Ali, with a chain of transmission traceable. Shu’bah narrated on the authority of Abi Ishaq said on the authority of Abdullah bin Murrah, on the authority of Al-Harith, on the authority of Ali, on the authority of a chain of narrators.
