An Nisa, 65 Ayah
4:65
فَلَا وَرَبِّكَ لَا يُؤۡمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيۡنَهُمۡ ثُمَّ لَا يَجِدُواْ فِيٓ أَنفُسِهِمۡ حَرَجٗا مِّمَّا قَضَيۡتَ وَيُسَلِّمُواْ تَسۡلِيمٗا ٦٥
Falā Wa Rabbika Lā Yu'uminūna Ĥattá Yuĥakkimūka Fīmā Shajara Baynahum Thumma Lā Yajidū Fī 'Anfusihim Ĥarajāan Mimmā Qađayta Wa Yusallimū Taslīmāan
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.
