Musnad Abu Ya'la al-Mawsili 150:325

Abu Hammam narrated to us, Ibn Wahb narrated to us, Amr ibn al-Harith informed me, from Ibn Shihab, from Urwah ibn al-Zubayr, from Aisha, who said: I saw the Prophet, may Allah bless him and grant him peace, screening me with his garment while I was looking at the Abyssinians as they were playing, and I was a young girl. So, estimate the estimation of a young girl who is eager and young in age. She said: It was a day of Eid, and the Abyssinians were playing with shields and spears. Either I asked the Messenger of Allah, may Allah bless him and grant him peace, or he said, "Do you desire to look?" I said, "Yes." So he made me stand behind him, with my cheek against his cheek, while he was saying, "Carry on, O Banu Arfada." Until, when I became bored, he said, "Is that enough for you?" I said, "Yes." He said, "Then go."
