The Cow - 2:42
Do not knowingly confuse the truth with falsehood, and do not conceal the truth.
The disbelievers are those who confuse truth with falsehood:
The Cave/18:56
We have sent the messengers only as bearers of glad tidings and warners. The disbelievers strive to destroy the truth with falsehood and falsehood. They ridiculed My signs and what they were warned about.
The Forgiver/40:5
Noah´s people denied before them, and many parties after them. Each party tried to neutralize their messengers. They argued with vain and false things to remove the truth. At last I seized them; how is My punishment?
The Family Of Imran/3:71
People of the Book! Why do you confuse right and wrong and knowingly conceal the truth?
The Cow/2:146
Those to whom We have given the Book recognize these truths as they recognize their children, yet a group of them knowingly conceal the truth.
The Family Of Imran/3:187
"Allah had taken a promise from those to whom the Book was given, saying, "You will certainly make it clear to the people and you will not conceal it."But they threw it behind their backs and sold it for a small price. What an evil exchange!"
