Surah Al-Nahl (The Bees), Verse 116

وَلَا تَقُوْلُوْا لِمَا تَصِفُ اَلْسِنَتُكُمُ الْكَذِبَ هٰذَا حَلٰلٌ وَّهٰذَا حَرَامٌ لِّتَفْتَرُوْا عَلَی اللّٰهِ الْكَذِبَ اِنَّ الَّذِیْنَ یَفْتَرُوْنَ عَلَی اللّٰهِ الْكَذِبَ لَا یُفْلِحُوْنَ ۟

Wa laa taqooloo limaa tasifu alsinatukumul kaziba haaza halaalunw wa haazaa haraamul litaftaroo 'alal laahil kazib; innal lazeena yaftaroona 'alal laahil kaziba laa yuflihoon

“But say not - for any false thing that your tongues may put forth,- "This is lawful, and this is forbidden," so as to ascribe false things to Allah. For those who ascribe false things to Allah, will never prosper.”
