Musnad Ahmad 1153:539

Muhammad ibn Mus'ab narrated to us, he said: Al-Awza'i narrated to us, from Az-Zuhri, from 'Urwah, from 'Aishah, she said: "The Messenger of Allah (peace and blessings of Allah be upon him) was in my room, shielding me with his garment, while I was looking at the Abyssinians as they played, until I was the one who became bored. So, estimate the capacity of a young girl who is eager for amusement."
