Narrated 'Aisha:
Once I saw Allah's Apostle at the door of my house while some Ethiopians were playing in the mosque (displaying their skill with spears). Allah's Apostle was screening me with his Rida' so as to enable me to see their display. ('Urwa said that 'Aisha said, "I saw the Prophet and the Ethiopians were playing with their spears.")
