Quran 4:65 — Surah An-Nisa, ayah 65

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

But no, by your Lord, they will not [truly] believe until they make you, [O Muhammad], judge concerning that over which they dispute among themselves and then find within themselves no discomfort from what you have judged and submit in [full, willing] submission

I tako Mi Gospodara tvoga, oni neće biti vjernici dok za sudiju u sporovima međusobnim tebe ne prihvate i da onda zbog presude tvoje u dušama svojim nimalo tegobe ne osjete i dok se sasvim ne pokore.
