Quran 42:21 Ash-Shura, ayah 21 of 53

أَمْ لَهُمْ شُرَكَـٰٓؤُا۟ شَرَعُوا۟ لَهُم مِّنَ ٱلدِّينِ مَا لَمْ يَأْذَنۢ بِهِ ٱللَّهُ ۚ وَلَوْلَا كَلِمَةُ ٱلْفَصْلِ لَقُضِىَ بَيْنَهُمْ ۗ وَإِنَّ ٱلظَّـٰلِمِينَ لَهُمْ عَذَابٌ أَلِيمٌ ۝٢١

42:21 Or have they partners (of Allah) who have made lawful for them in religion that which Allah allowed not? And but for a decisive word (gone forth already), it would have been judged between them. Lo! for wrong-doers is a painful doom.
