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

For He has decreed that the truth shall prevail, and the falsehood shall vanish, in spite of the evildoers.

[8:7] Recall that GOD promised you victory over a certain group, but you still wanted to face the weaker group. It was GOD's plan to establish the truth with His words, and to defeat the disbelievers.

[8:9] Thus, when you implored your Lord to come to the rescue, He responded to you: "I am supporting you with one thousand angels in succession."
