6:35If you find their rejection hard to bear, then if you can, seek a tunnel into the earth, or a stairway into the heaven, and bring them a sign. Had God willed, He could have gathered them to guidance. So do not be of the ignorant.

6:107Had God willed, they would not have practiced idolatry. We did not appoint you as a guardian over them, and you are not a manager over them.

6:112Likewise, We have assigned for every prophet an enemy—human and jinn devils—inspiring one another with fancy words in order to deceive. But had your Lord willed, they would not have done it. So leave them to their fabrications.

6:137Likewise, their idols entice many idolaters to kill their children, in order to lead them to their ruin, and confuse them in their religion. Had God willed, they would not have done it; so leave them to their fraud.

6:148The polytheists will say, “Had God willed, we would not have practiced idolatry, nor would have our forefathers, nor would we have prohibited anything.” Likewise those before them lied, until they tasted Our might. Say, “Do you have any knowledge that you can produce for us? You follow nothing but conjecture, and you only guess.”

6:149Say, “To God belongs the conclusive argument. Had He willed, He would have guided you all.”
