The Cow - 2:42
Do not knowingly confuse the truth with falsehood, and do not conceal the truth.
What is meant by "truth":
The Cow/2:213
Mankind were a single community. Allah sent messengers as bearers of glad tidings and warners and sent down with them the Book containing the truth so that they might judge between the people in matters wherein they differed. But those who were given the Book disputed about it out of envy among themselves after clear proofs had come to them. But Allah, by His permission, brought the believers to the truth about which they differed. Allah guides whom He wills/whosoever He wills.
