It is narrated from Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The best sacrifice is a horned ram, and the best shroud is a hullah (a two-piece garment)." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Sa'd al-Zuraqi (may Allah be pleased with him) (who was a Companion) that he went out to buy sacrificial animals. He pointed to a ram whose head was black and which had horns, and which was not the tallest of the rams, and said: This looks exactly like the ram that the Messenger of Allah (peace and blessings be upon him) sacrificed. This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it.
