Quran 10.105-107
And, (O Muhammad) set thy purpose resolutely for religion, as a man by nature upright, and be not of those who ascribe partners (to Allah). And cry not, beside Allah, unto that which cannot profit thee nor hurt thee, for if thou didst so then wert thou of the wrong-doers. If Allah afflicteth thee with some hurt, there is none who can remove it save Him; and if He desireth good for thee, there is none who can repel His bounty. He striketh with it whom He will of his bondmen. He is the Forgiving, the Merciful.
