Sayyiduna Abu Sa'd al-Khayr (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "Perform ablution after eating something cooked on fire, by which the pots have been brought to the boil!"
Imam al-Tabarani recorded this report in al-Mu'jam al-Kabir; its chain contains a narrator, Firas al-Sha'bani, who is majhul (unknown).
