Prohibition of Lying Against Allah

وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ كَذَّبَ بِـَٔايَـٰتِهِۦٓ ۗ إِنَّهُۥ لَا يُفْلِحُ ٱلظَّـٰلِمُونَ

And who is more unjust than one who invents about Allāh a lie or denies His verses? Indeed, the wrongdoers will not succeed.

قَالَ لَهُم مُّوسَىٰ وَيْلَكُمْ لَا تَفْتَرُوا۟ عَلَى ٱللَّهِ كَذِبًا فَيُسْحِتَكُم بِعَذَابٍ ۖ وَقَدْ خَابَ مَنِ ٱفْتَرَىٰ

Moses said to them [i.e., the magicians summoned by Pharaoh], "Woe to you! Do not invent a lie against Allāh or He will exterminate you with a punishment; and he has failed who invents [such falsehood]."
