Last week, the UK-based Syrian Observatory of Human Rights reported resentment among Syrian Daesh fighters, who believed their pay was being cut "according to the desire of the organization’s leadership to raise the wages of Arab and foreigner fighters at the expense of the local fighters."
The monitoring group reported that Daesh members in Raqqa, which the terrorist group captured in January 2014, "are beginning to borrow money and the members were [indicating] that their income is declining, which weakened their purchasing power."
According to a leaked Daesh document, a pay cut has in fact been imposed on all fighters. The document was obtained by researcher Aymenn Jawad Al-Tamimi, who published it on his website with a translation.
"Jihad of wealth has been mentioned with jihad of soul in the Qur'an in ten cases, and in nine of those cases jihad of wealth has been presented beforehand over jihad of the soul, and only in one case has jihad of the soul been presented beforehand over jihad of wealth," wrote Daesh.
"So on account of the exceptional circumstances the Islamic State (Daesh) is facing, it has been decided to reduce the salaries that are paid to all mujahideen by half, and it is not allowed for anyone to be exempted from this decision, whatever his position. Let it be known that work will continue to distribute provisions twice every month, as usual."
In October the US-led coalition carrying out airstrikes in Iraq and Syria announced the launch of Operation Tidal Wave II, which also targets the Daesh oil distribution chain.
