Universal Application of Shariah

وَلْيَحْكُمْ أَهْلُ ٱلْإِنجِيلِ بِمَآ أَنزَلَ ٱللَّهُ فِيهِ ۚ وَمَن لَّمْ يَحْكُم بِمَآ أَنزَلَ ٱللَّهُ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْفَـٰسِقُونَ

And let the People of the Gospel judge by what Allāh has revealed therein. And whoever does not judge by what Allāh has revealed - then it is those who are the defiantly disobedient.
