Quran 39:38 — The Throngs (Al-Zumar)

If you ask them, "Who created the heavens and the earth?" they will say, "GOD." Say, "Why then do you set up idols beside GOD? If GOD willed any adversity for me, can they relieve such an adversity? And if He willed a blessing for me, can they prevent such a blessing?" Say, "GOD is sufficient for me." In Him the trusters shall trust.

[39:37] And whomever GOD guides, nothing can send him astray. Is GOD not Almighty, Avenger?

[39:39] Say, "O my people, do your best and I will do my best; you will surely find out.
