Musnad Ahmad 30:627

'Abd al-Razzaq narrated to us, my father informed me, Mina informed us, from Abu Hurayrah, who said: I was sitting with the Prophet, may Allah bless him and grant him peace, when a man came and said: "O Messenger of Allah, curse Himyar." He turned away from him. Then he came to him from another side, and he turned away from him, while he was saying: "Curse Himyar." The Messenger of Allah, may Allah bless him and grant him peace, said: "May Allah have mercy on Himyar; their mouths are peace, their hands are food, and they are a people of security and faith."
