Musnad Ahmad 25:457

'Affan narrated to us, Shu'bah narrated to us, from 'Amr ibn Murrah, from Yahya ibn al-Jazzar, that Ibn 'Abbas said: "I passed by, along with a boy from Banu Hashim, on a donkey, and we left it to eat from some herbs in front of the Messenger of Allah, may Allah bless him and grant him peace, and he did not turn away. Then two young girls came running until they took hold of the knees of the Messenger of Allah, may Allah bless him and grant him peace, and he did not turn away."
