It is reported about Sayyiduna Anas (may Allah be pleased with him) as well that he placed his fingers on his ears and said: May they become deaf if I did not hear the Prophet (peace and blessings be upon him) say: "Perform ablution after (eating) something cooked on fire!"
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Khalid bin Yazid bin Abi Malik, who is a kadhdhab (liar).
