Quran 2:14 — The Heifer (Al-Baqarah)

When they meet the believers, they say, "We believe," but when alone with their devils, they say, "We are with you; we were only mocking."

[2:13] When they are told, "Believe like the people who believed," they say, "Shall we believe like the fools who believed?" In fact, it is they who are fools, but they do not know.

[2:15] GOD mocks them, and leads them on in their transgressions, blundering.
