Quran 3:173 — The Amramites (Ali-'Imran)

When the people say to them, "People have mobilized against you; you should fear them," this only strengthens their faith, and they say, "GOD suffices us; He is the best Protector."

[3:172] For those who respond to GOD and the messenger, despite the persecution they suffer, and maintain their good works, and lead a righteous life, a great reward.

[3:174] They have deserved GOD's blessings and grace. No harm ever touches them, for they have attained GOD's approval. GOD possesses infinite grace.
