﴿ وَلَا تَقُولُوا۟ لِمَا تَصِفُ أَلْسِنَتُكُمُ ٱلْكَذِبَ هَٰذَا حَلَٰلٌۭ وَهَٰذَا حَرَامٌۭ لِّتَفْتَرُوا۟ عَلَى ٱللَّهِ ٱلْكَذِبَ ۚ إِنَّ ٱلَّذِينَ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ لَا يُفْلِحُونَ ﴾
“Hence, do not utter falsehoods by letting your tongues determine [at your own discretion], "This is lawful and that is forbidden", thus attributing your own lying inventions to God: for, behold, they who attribute their own lying inventions to God will never attain to a happy state!”
