Sura al-Naḥl 16:116

وَلَا تَقُولُوا۟ لِمَا تَصِفُ أَلْسِنَتُكُمُ ٱلْكَذِبَ هَٰذَا حَلَٰلٌ وَهَٰذَا حَرَامٌ لِّتَفْتَرُوا۟ عَلَى ٱللَّـهِ ٱلْكَذِبَ إِنَّ ٱلَّذِينَ يَفْتَرُونَ عَلَى ٱللَّـهِ ٱلْكَذِبَ لَا يُفْلِحُونَ

wa-lā taqūlū li-mā taṣifu alsinatukumu l-kadhiba hādhā ḥalālun wa-hādhā ḥarāmun li-taftarū ʿalā allāhi l-kadhiba inna lladhīna yaftarūna ʿalā allāhi l-kadhiba lā yufliḥūna

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.

Sura al-Isrāʾ 17:73

وَإِن كَادُوا۟ لَيَفْتِنُونَكَ عَنِ ٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ لِتَفْتَرِىَ عَلَيْنَا غَيْرَهُۥ وَإِذًا لَّٱتَّخَذُوكَ خَلِيلًا

wa-in kādū la-yaftinūnaka ʿani alladhī awḥaynā ilayka li-taftariya ʿalaynā ghayrahu waidhan la-ittakhadhūka khalīlan

And their purpose was to tempt thee away from that which We had revealed unto thee, to substitute in our name something quite different; (in that case), behold! they would certainly have made thee (their) friend!
