مسند أحمد

It was narrated that Malik bin Aws said: ‘Umar sent for me... and he mentioned a similar hadeeth. He said: The wealth of Banun-Nadeer was among the fai` that Allah granted to His Messenger for which the Muslims made no expedition with either cavalry or camelry (cf. al-Hashr 59:6). He allocated some of it for his family`s maintenance for one year, and what was left he spent on horses and weapons in preparation for jihad for the sake of Allah, may He be glorified and exalted.
