'Umar bin Khattab (may Allah be pleased with him) says that the wealth of the tribe of Banu Nadir, who were Jews, was among those properties which Allah, the Exalted, granted to His Messenger (peace be upon him) as «فے» 1. The Muslims had neither made their horses gallop for it nor their camels. This entire property was purely for Allah’s Messenger (peace be upon him). The Messenger of Allah (peace be upon him) would set aside from it a year’s provision for his family, and then whatever remained, he would spend on horses and weapons in preparation for jihad. Imam Tirmidhi says:
1- This hadith is Hasan Sahih,
2- Sufyan bin ‘Uyaynah narrated this hadith from Ma’mar, from Ibn Shihab.
