This hadith has been narrated by Hisham with the same chain of transmitters but (the narrators) did not make mention of the mosque.
Sahih Muslim Book 8, Hadith 22
← Previous Hadith '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 (ﷺ) 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.

Sahih Muslim Book 8, Hadith 21 Next Hadith → I like to see them (fighting). She further said: The Messenger of Allah (ﷺ) stood up and I stood at the door (behind him) and saw (this fight) between his ears and his shoulders they played in the mosque. 'Ata' (one of the narra- tors) said: Were they persians or Abyssinians? Ibn 'Atiq told me they were Abyssinians.
