The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 1943
'A'isha reported that some Abyssinians came and gave a demonstration of armed fight on the 'Id day in the mosque. The Apostle of Allah (may peace be upon him) invited me (to see that fight). I placed my head on his shoulder and began to see their sport till it was I who turned away from watching them.
