Hazrat Sa‘eed bin Musayyib (rahimahullah) has mentioned, “Hazrat Sa’d (radhiyallahu ‘anhu) was an excellent archer.” (Taareekh-ul-Islam 4/216)
Imaam Zuhri (rahimahullah) has mentioned, “During the Battle of Uhud, Hazrat Sa’d (radhiyallahu ‘anhu) killed three disbelievers with the same arrow that was fired at him three times. The disbelievers had initially fired the arrow. Hazrat Sa’d (radhiyallahu ‘anhu) took the arrow and fired it back at the disbelievers, killing one of them. The disbelievers then fired the same arrow back, after which Hazrat Sa’d (radhiyallahu ‘anhu) took it and fired it back at them, killing another disbeliever. The disbelievers then fired the same arrow back for a third time. Hazrat Sa’d (radhiyallahu ‘anhu) took the arrow and fired it back at them, killing a third disbeliever. Seeing that Hazrat Sa’d (radhiyallahu ‘anhu) had killed three disbelievers with the same arrow, the people were amazed.
