Hazrat Sa’d (radhiyallahu ‘anhu) was part of the army that Rasulullah (sallallahu ‘alaihi wasallam) had sent under Hazrat ‘Ubaidah bin Haarith (radhiyallahu ‘anhu) to Raabigh in order to intercept the caravan of the Quraish. During this expedition, the Sahaabah (radhiyallahu ‘anhum) and the Quraish fired arrows at one another, and the first Muslim to fire an arrow in the path of Allah was Hazrat Sa’d (radhiyallahu ‘anhu).
It was regarding this occasion that Hazrat Sa’d (radhiyallahu ‘anhu) recited the following poetry:
ألا هل أتى رسول الله أني حميت صحابتي بصدور نبلي
أذود بها عدوهم ذيادا بكل حزونة وبكل سهل
فما يعتد رام من معد بسهم في سبيل الله قبلي
Did the news reach Rasulullah (sallallahu ‘alaihi wasallam) that I protected my companions with my arrows?
I effectively repelled their enemies with my arrows, in every hard land and in every soft land.
Hence, no archer from Ma’ad, before me, is counted among those who fired an arrow in the path of Allah Ta‘ala.
