The Hadith: 'The Prophet ate a piece of meat from the shoulder of a lamb and offered Salah'

Q: Is the following account considered a true Hadith: "He (the Prophet, peace be upon him) cut a piece of meat from the shoulder of a lamb, ate it, and then offered Salah (Prayer)."

A: It was reported by Ahmad and Al-Tabarany in Al-Kabir, on the authority of `Abdullah ibn Al-Haryth ibn Nawfal, that Um Hakim bint Al-Zubayr told him: The Messenger of Allah (peace be upon him) entered to Duba`ah, and cut off a slice of meat from the shoulder of a sheep and ate from it. Then he offered Salah without performing Wudu' (ablution) after eating. Al-Haythamy said in Majma` Al-Zawa'id: "The Hadith was narrated by Rijal Al-Sahih (narrators of Hadith compiled by Al-Bukhari and/or Muslim)." (Part No. 3; Page No. 277) It was reported by Imam Ahmad on the authority of Um Hakim bint Al-Zubayr that she said: I handed to the Prophet of Allah (peace be upon him) shoulder meat of which he ate, and then he offered Salah. He said in Majma` Al-Zawa'id: "Its narrators are Thiqah (trustworthy)."May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
