Musnad Ahmad 789:4

Muhammad ibn Abi ‘Adi narrated to us, from Sulayman, from Abu ‘Uthman, from Abu Barzah, who said: There was a riding beast, or a she-camel, or a camel, upon which was some of the people’s luggage, and upon it was a slave girl. They took a path between two mountains, and the road became narrow for them. She saw the Messenger of Allah (peace and blessings of Allah be upon him) and said: "Hul, hul! O Allah, curse it!" The Messenger of Allah (peace and blessings of Allah be upon him) said: "Who is the owner of this slave girl? Let no riding beast, or she-camel, or camel upon which is the curse of Allah accompany us."
