Quran 3:121 — The Amramites (Ali-'Imran)

Recall that you (Muhammad) were among your people when you set out to assign to the believers their positions for battle. GOD is Hearer, Omniscient.

[3:120] When anything good comes your way they hurt, and when something bad happens to you they rejoice. If you steadfastly persevere, and maintain righteousness, their schemes will never hurt you. GOD is fully aware of everything they do.

[3:122] Two groups among you almost failed, but GOD was their Lord. In GOD the believers shall trust.
