فَلَا وَرَبِّكَ لَا يُؤۡمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيۡنَهُمۡ ثُمَّ لَا يَجِدُواْ فِيٓ أَنفُسِهِمۡ حَرَجٗا مِّمَّا قَضَيۡتَ وَيُسَلِّمُواْ تَسۡلِيمٗا

Falaa wa Rabbika laa yu'minoona hattaa yuhakkimooka fee maa shajara bainahum summa laa yajidoo feee anfusihim harajam mimmaa qadaita wa yusal limoo tasleemaa

But no, by thy Lord, they can have no (real) Faith, until they make thee judge in all disputes between them, and find in their souls no resistance against Thy decisions, but accept them with the fullest conviction.

— An-Nisa' (ٱلنِّسَاء), 4:65
