Quran 8:48 — The Spoils of War (Al-Anfal)

The devil had adorned their works in their eyes, and said, "You cannot be defeated by any people today," and "I will be fighting along with you." But as soon as the two armies faced each other, he turned back on his heels and fled, saying, "I disown you. I see what you do not see. I am afraid of GOD. GOD's retribution is awesome."

[8:47] Do not be like those who left their homes grudgingly, only to show off, and in fact discouraged others from following the path of GOD. GOD is fully aware of everything they do.

[8:49] The hypocrites and those who harbored doubt in their hearts said, "These people are deceived by their religion." However, if one puts his trust in GOD, then GOD is Almighty, Most Wise.
