It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) slaughtered a horned ram at the Eid prayer ground, then said: "O Allah, this is on my behalf and on behalf of those of my Ummah who have not offered a sacrifice." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it.
