Musnad Ahmad 1153:287

Ibn Numayr narrated to us, he said: Hisham narrated to us, from his father, from Aisha: "The Abyssinians were playing in the presence of the Messenger of Allah, may Allah bless him and grant him peace, on a day of Eid. She said: So I looked from over his shoulder, and the Messenger of Allah, may Allah bless him and grant him peace, lowered his shoulders for me, and I continued looking at them from over his shoulder until I was satisfied, then I turned away."
