Narrated Salama bin Al-Akwa`: The Prophet passed by some persons of the tribe of Aslam practicing archery (i.e. the throwing of arrows) Allah's Apostle said, O offspring of Ishmael! Practice archery (i.e. arrow throwing) as your father was a great archer (i.e. arrow-thrower). I am with (on the side of) the son of so-and-so-. Hearing that, one of the two teams stopped throwing. Allah's Apostle asked them, ' Why are you not throwing? They replied, O Allah's Apostle! How shall we throw when you are with the opposite team? He said, Throw, for I am with you all.
