Quran 3:154 — The Amramites (Ali-'Imran)

After the setback, He sent down upon you peaceful slumber that pacified some of you. Others among you were selfishly concerned about themselves. They harbored thoughts about GOD that were not right—the same thoughts they had harbored during the days of ignorance. Thus, they said, "Is anything up to us?" Say, "Everything is up to GOD." They concealed inside themselves what they did not reveal to you. They said, "If it was up to us, none of us would have been killed in this battle." Say, "Had you stayed in your homes, those destined to be killed would have crawled into their death beds." GOD thus puts you to the test to bring out your true convictions, and to test what is in your hearts. GOD is fully aware of the innermost thoughts.

[3:153] Recall that you rushed (after the spoils), paying no attention to anyone, even when the messenger was calling from behind you. Consequently, He substituted one misery for another, that you may not grieve over anything you had missed, or agonize over any hardship you had suffered. GOD is Cognizant of everything you do.

[3:155] Surely, those among you who turned back the day the two armies clashed have been duped by the devil. This reflects some of the (evil) works they had committed. GOD has pardoned them. GOD is Forgiver, Clement.
