Saad bin Malik reported,

I am the first among the Arabs to shoot an arrow in the cause of Allah. We used to go out on military campaigns with the Messenger of Allah ﷺ having nothing to eat but the leaves of the hubla tree and these acacia trees, until one of us would relieve himself like a sheep, his droppings unmixed. And now Banu Asad come to instruct me in religion. If that were the case, I would indeed have failed and my deeds would be lost.

Ahmad 1566

Sahih

حدثنا يحيى بن سعيد حدثنا إسماعيل حدثنا قيس قال سمعت

سعد بن مالك يقول

إني لأول العرب رمى بسهم في سبيل الله ولقد أتينا نغزو مع رسول الله ﷺ وما لنا طعام نأكله إلا ورق الحبلة وهذا السمر حتى إن أحدنا ليضع كما تضع الشاة ما له خلط ثم أصبحت بنو أسد يعزروني على الدين لقد خبت إذن وضل عملي
