Ideas are mentioned in the Quran in these verses:

[4:108] They hide from the people, and do not care to hide from God, though He is with them as they harbor ideas He dislikes. God is fully aware of everything they do.

[21:65] Yet, they reverted to their old ideas: “You know full well that these cannot speak.”

[33:32] O wives of the prophet, you are not the same as any other women, if you observe righteousness. (You have a greater responsibility.) Therefore, you shall not speak too softly, lest those with disease in their hearts may get the wrong ideas; you shall speak only righteousness.
