Qur'an 42:21 · Ash-Shura

أَمْ لَهُمْ شُرَكَٰٓؤُا۟ شَرَعُوا۟ لَهُم مِّنَ ٱلدِّينِ مَا لَمْ يَأْذَنۢ بِهِ ٱللَّهُ ۚ وَلَوْلَا كَلِمَةُ ٱلْفَصْلِ لَقُضِىَ بَيْنَهُمْ ۗ وَإِنَّ ٱلظَّٰلِمِينَ لَهُمْ عَذَابٌ أَلِيمٌۭ

(21) Or have they partners [i.e., other deities] who have ordained for them a religion to which Allāh has not consented? But if not for the decisive word,[1420] it would have been concluded between them. And indeed, the wrongdoers will have a painful punishment.
