Sura al-Māʾidah 5:49

وَأَنِ ٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّـهُ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ وَٱحْذَرْهُمْ أَن يَفْتِنُوكَ عَنۢ بَعْضِ مَآ أَنزَلَ ٱللَّـهُ إِلَيْكَ فَإِن تَوَلَّوْا۟ فَٱعْلَمْ أَنَّمَا يُرِيدُ ٱللَّـهُ أَن يُصِيبَهُم بِبَعْضِ ذُنُوبِهِمْ وَإِنَّ كَثِيرًا مِّنَ ٱلنَّاسِ لَفَٰسِقُونَ

And this (He commands): Judge thou between them by what Allah hath revealed, and follow not their vain desires, but beware of them lest they beguile thee from any of that (teaching) which Allah hath sent down to thee. And if they turn away, be assured that for some of their crime it is Allah's purpose to punish them. And truly most men are rebellious.
