Quran 28:50 — History (Al-Qasas)

If they fail to respond to you, then know that they follow only their own opinions. Who is farther astray than those who follow their own opinions, without guidance from GOD? GOD does not guide such wicked people.

[28:49] Say, "Then produce a scripture from GOD with better guidance than the two, so I can follow it, if you are truthful."

[28:51] We have delivered the message to them, that they may take heed.
