I say, and with Allah's success: It is not considered one of the nullifiers of ablution; this is supported by what was narrated from Jabir , who said: "The last of the matters of the Messenger of Allah  was that he did not perform ablution after eating what the fire touched," in Sahih Ibn Khuzaymah 1: 28, and Sahih Ibn Hibban 3: 417. And from Ibn Abbas : "Indeed, the Messenger of Allah  ate the shoulder of a sheep and then prayed without performing ablution," and from Ja'far ibn Amr ibn Umayyah al-Damri from his father: "He saw the Messenger of Allah  cutting from a shoulder, eating from it, and then praying without performing ablution," in Sahih Muslim 1: 273, and Allah knows best.
