Quran 27:13 — The Ant (Al-Naml)

When our miracles were presented to them, clear and profound, they said, "This is obviously magic."

[27:12] "Put your hand in your pocket; it will come out white, without a blemish. These are among nine miracles to Pharaoh and his people, for they are wicked people."

[27:14] They rejected them and were utterly convinced of their wrong ways, due to their arrogance. Note the consequences for the evildoers.
