Quran 8:13 — The Spoils of War (Al-Anfal)

ذٰلِكَ بِأَنَّهُم شاقُّوا اللَّهَ وَرَسولَهُ ۚ وَمَن يُشاقِقِ اللَّهَ وَرَسولَهُ فَإِنَّ اللَّهَ شَديدُ العِقابِ

This is what they have justly incurred by fighting GOD and His messenger. For those who fight against GOD and His messenger, GOD's retribution is severe.

[8:12] Recall that your Lord inspired the angels: "I am with you; so support those who believed. I will throw terror into the hearts of those who disbelieved. You may strike them above the necks, and you may strike even every finger."

[8:14] This is to punish the disbelievers; they have incurred the retribution of Hell.
