Why are many islamic-run countries in financial poverty?
Prominent Egyptian Salafi Shaykh Abu-Ishaq al-Huwayni explains that Muslims’ financial difficulties are due to the fact that they have abandoned jihad (holy war to kill or convert infidels). The solution? Go on jihadist raids a few times a year, and bring back prisoners, including women and children, which can be sold in the market like groceries to bring in extra income when times are tough.
