Mukhtasar Bukhari

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says: I saw the Messenger of Allah (peace and blessings be upon him) one day at the door of my room, and the Abyssinians were playing in the mosque, and the Messenger of Allah (peace and blessings be upon him) was shielding me with his cloak, and I was watching their play. In another narration, it is mentioned that they were playing with their swords.
