Musnad Ahmad 25:1315

Muhammad ibn Ja‘far narrated to us, Shu‘bah and Hajjaj narrated to us, from Shu‘bah, from ‘Amr ibn Murrah, from Yahya ibn al-Jazzar, from Ibn ‘Abbas: "The Prophet, peace and blessings of Allah be upon him, was praying, and a kid (young goat) began wanting to pass in front of the Prophet, peace and blessings of Allah be upon him. So it began to move forward and backward—Hajjaj said: it was avoiding him and moving backward—until the kid jumped."
