Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: I was with the Prophet (peace and blessings be upon him) when a man came, I think he was from the tribe of Qays, and said: "O Messenger of Allah, curse Himyar." The Messenger of Allah (peace and blessings be upon him) turned away from him. He came from the other side, and the Messenger of Allah (peace and blessings be upon him) again turned away from him. Then he came from the third side, and he (peace and blessings be upon him) again turned away from him. Then the Messenger of Allah (peace and blessings be upon him) said: "May Allah have mercy on Himyar. Their hearts are (filled with) Islam, their deeds are peace, their hands are food (that they give to others), and they are a people of security and faith."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yahya bin Abi Kathir except Isma'il bin Mirsal, and his son is alone in narrating it from him."
This is how it appears in the Dar al-Haramayn edition, and probably the correct name is "Amr bin Khulayf".
