innovation in religion (bid'ah)

مَا جَعَلَ ٱللَّهُ مِنۢ بَحِيرَةٍ وَلَا سَآئِبَةٍ وَلَا وَصِيلَةٍ وَلَا حَامٍ ۙ وَلَـٰكِنَّ ٱلَّذِينَ كَفَرُوا۟ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ ۖ وَأَكْثَرُهُمْ لَا يَعْقِلُونَ

Allāh has not appointed [such innovations as] baḥīrah or sā’ibah or waṣīlah or ḥām. But those who disbelieve invent falsehood about Allāh, and most of them do not reason.

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

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, it would have been concluded between them. And indeed, the wrongdoers will have a painful punishment.
