The presence of spearmen (with their spears) in the mosque (is permissible)

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