6:21Who does greater wrong than someone who fabricates lies against God, or denies His revelations? The wrongdoers will not succeed.

6:93Who does greater wrong than someone who invents falsehood against God, or says, “It was revealed to me,” when nothing was revealed to him, or says, “I will reveal the like of what God revealed”? If only you could see the wrongdoers in the floods of death, as the angels with arms outstretched: “Give up your souls. Today you are being repaid with the torment of shame for having said about God other than the truth, and for being too proud to accept His revelations.”

6:144And two of the camels, and two of the cattle. Say, “Did He forbid the two males, or the two females, or what the wombs of the two females contain? Were you present when God enjoined this upon you?” Who does greater wrong than he who invents lies and attributes them to God, in order to mislead people without knowledge? God does not guide the wicked people.

6:157Or lest you say, “Had the Scripture been revealed to us, we would have been better guided than they.” Clarification has come to you from your Lord, and guidance, and mercy. Who then does greater wrong than he who gives the lie to God's messages, and turns away from them? We will repay those who turn away from Our messages with the worst kind of punishment, because of their turning away.
