Musnad Abu Ya'la al-Mawsili 162:11

'Amr ibn al-Dahhak narrated to us, my father narrated to us, Ibn Jurayj narrated to us, Muhammad ibn 'Umar ibn 'Ali narrated to us, from al-'Abbas ibn 'Ubayd Allah ibn 'Abbas, from al-Fadl ibn 'Abbas, who said: The Prophet, may Allah bless him and grant him peace, visited al-'Abbas in a desert area of ours. There was a dog and a donkey of ours grazing. The Prophet, may Allah bless him and grant him peace, prayed the 'Asr prayer while they were in front of him, and they were neither driven away nor moved back.
