النساۤء — An-Nisa' Ayat 65
فَلَا وَرَبِّكَ لَا يُؤْمِنُوْنَ حَتّٰى يُحَكِّمُوْكَ فِيْمَا شَجَرَ بَيْنَهُمْ ثُمَّ لَا يَجِدُوْا فِيْٓ اَنْفُسِهِمْ حَرَجًا مِّمَّا قَضَيْتَ وَيُسَلِّمُوْا تَسْلِيْمًا
Falā wa rabbika lā yu'minūna ḥattā yuḥakkimūka fīmā syajara bainahum ṡumma lā yajidū fī anfusihim ḥarajam mimmā qaḍaita wa yusallimū taslīmā(n).
"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."
