Surah An-Nisa — Ayah 107 (4:107)
وَلَا تُجَٰدِلۡ عَنِ ٱلَّذِينَ يَخۡتَانُونَ أَنفُسَهُمۡۚ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ خَوَّانًا أَثِيمٗا ١٠٧
English translation (Saheeh International)
And do not argue on behalf of those who deceive themselves. Indeed, Allāh loves not one who is a habitually sinful deceiver.
Brief commentary
Do not argue on behalf of any person who commits a sin denying it, until you come to know more about the matter. Allah does not love these deceitful liars.
