Musnad Ahmad 324:1

Hushaym narrated to us, from Abu Bishr, from Ali ibn Bilal, from some people of the Ansar who said: "We used to pray the Maghrib prayer with the Messenger of Allah, may Allah bless him and grant him peace, then we would depart and compete in archery until we reached our homes, and the landing spots of our arrows would not be hidden from us."
