And do not argue on behalf of those who deceive themselves. Indeed, (4:107)

Almuntakhab Fi Tafsir Alquran Alkarim

Nor should you plead on behalf of those who deceive their own minds, their views and their hopes and assert what is false and lead others into error; Allah detests the one who deceitfully violates faith and betrays trust, whose name has become a byword of perfidy and crime

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(4:107) Do not plead for those who are dishonest to themselves; *141 Allah does not love him who betrays trust and persists in sin.

And do not argue on behalf of those who deceive themselves. Indeed, meaning

*141). Whoever commits a breach of trust with others in fact commits a breach of trust with his own self first. For the powers of his head and heart have been placed at his disposal as a trust, and by misusing them he is forcing those powers to support him in acts which involve a breach of trust. In doing so the person concerned suppresses his conscience, which God has placed as a sentinel over his moral conduct, with the result that it is rendered incapable of preventing him from acts of wrong and iniquity. It is only after a man has already carried out this cruel suppression of conscience within himself that he is able to commit acts of sin and iniquity outwardly.
 

And do not argue on behalf of those who deceive themselves. Indeed, meaning in Urdu

جو لو گ اپنے نفس سے خیانت کرتے ہیں تم اُن کی حمایت نہ کرو اللہ کو ایسا شخص پسند نہیں ہے جو خیانت کار اور معصیت پیشہ ہو
