Al-An'am - 6:107

وَلَوْ شَاء اللّهُ مَا أَشْرَكُواْ وَمَا جَعَلْنَاكَ عَلَيْهِمْ حَفِيظًا وَمَا أَنتَ عَلَيْهِم بِوَكِيلٍ
[6:107]
And if Allah had pleased, they would not have set up others (with Him) and We have not appointed you a keeper over them, and you are not placed in charge of them.
If it had been Allah's plan, they would not have taken false gods: but We made thee not one to watch over their doings, nor art thou set over them to dispose of their affairs.
Had Allah willed, they had not been idolatrous. We have not set thee as a keeper over them, nor art thou responsible for them.
