The noble wife of the Prophet Muhammad (peace be upon him), Umm Habibah (may Allah be pleased with her), narrated from the Prophet (peace be upon him) that he said: "Perform ablution (wudu) after (eating or drinking) whatever has been touched by fire (cooked on fire)."

Explanation & Benefits
Hafiz Abdush Shakoor Tirmidhi
Benefits: In another hadith, it is narrated from Sayyiduna Amr ibn Umayyah Damri radi Allahu anhu that he said: I saw the Noble Prophet sallallahu alayhi wa sallam cutting and eating the meat from the shoulder of a goat. Then he was called for prayer, so he stood up and threw away the knife. He sallallahu alayhi wa sallam performed the prayer but did not perform ablution (wudu). (Bukhari, Book of Ablution, No. 208. See also Hadith No. 652)
Apparently, there seems to be a contradiction between the two hadiths. However, the first narration is abrogated (mansukh) and the second is the abrogating (nasikh). As Sayyiduna Jabir radi Allahu anhu states: Abandoning ablution (wudu) after eating something cooked with fire was the last of the two practices of the Messenger of Allah sallallahu alayhi wa sallam. (Sunan Abi Dawud, Book of Purification, No. 192. Sunan Nasa’i, No. 185. Sahih Abi Dawud, No. 177)
