And who is more unjust than one who invents about Allah a lie or denies His verses? (Quran 6:21)

"And who is more unjust than one who invents about Allah a lie or denies His verses? Indeed, the wrongdoers will not succeed." (Quran 6:21)

This verse emphasizes the grave sin of inventing lies about Allah and denying His verses. It highlights the fact that those who commit this injustice will never succeed in the Hereafter. Inventing lies about Allah means attributing to Him things that are not true or making false claims about His attributes or actions. Denying His verses means rejecting the truthfulness and validity of the Quran and the other revelations sent by Allah.

The verse points out that this is one of the most unjust acts a person can commit because it involves distorting the truth and misleading people away from the path of Allah. It is a betrayal of the trust that Allah has placed in human beings to convey His message to others.

The phrase "the wrongdoers will not succeed" indicates that those who commit this injustice will face severe consequences both in this world and in the Hereafter. They will not be successful in achieving their goals and will ultimately face the punishment of Allah for their actions. This serves as a warning to those who might be tempted to engage in such behavior, urging them to seek the truth and avoid spreading falsehood.

In this verse (Quran 6:21), Allah highlights the severity of committing the sin of inventing lies about Him or denying His verses. It is considered the greatest injustice and wrongdoing one can commit because it is a direct violation of the truth and leads to falsehood.

Allah emphasizes that those who engage in such behavior will not succeed, meaning they will not attain success in this life or the hereafter. They will face the consequences of their actions and will be held accountable for their denial of the truth.

The verse also underscores the importance of upholding the truth and avoiding falsehood in one's speech and actions. It serves as a reminder to stay away from any act of deception or dishonesty, especially when it comes to matters related to Allah and His religion.
