Is He then Who watches every soul as to what it earns? And yet they give associates to Allah! Say: Give them a name; nay, do you mean to inform Him of what He does not know in the earth, or (do you affirm this) by an outward saying? Rather, their plans are made to appear fair-seeming to those who disbelieve, and they are kept back from the path; and whom Allah makes err, he shall have no guide.

I found her and her people adoring the sun instead of Allah, and the Shaitan has made their deeds fair-seeming to them and thus turned them from the way, so they do not go aright

And most surely they turn them away from the path, and they think that they are guided aright:

Surely those who disbelieve and turn away from Allah's way and oppose the Messenger after that guidance has become clear to them cannot harm Allah in any way, and He will make null their deeds.
