note/14:3-4(people go astray out of their own choice)

We have not sent any messenger except in the tongue of his people so that he would make things clear for them. God then sends astray whom He wills and guides whom He wills. He is the Dignified, the Wise. 14:4

We have in the verse immediately before 14:4 evidence that the ones who are led astray are those who choose by themselves to go astray (and not the ones whom God Himself leads astray):

The ones who prefer the worldly life over the Hereafter, repel from the path of God and seek to have it crooked; they are in extreme misguidance indeed. 14:3

Such people go astray out of their own choice. It follows that the correct meaning of verse 4 is that God leaves to go astray those who choose themselves to go astray.

With this confirmation there is no contradiction with the other verse referred to by the author:

Say, "Does any of your partners guide to the truth?" Say, "God guides to the truth. So is One who guides to the truth more worthy of being followed, or one who does not guide unless he is guided? What is the matter with you? How do you judge?" 10:35
