Quran 4:65 from Surah An-Nisaa on Divine Marvels.
فَلَا وَرَبِّكَ لَا يُؤۡمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيۡنَهُمۡ ثُمَّ لَا يَجِدُواْ فِيٓ أَنفُسِهِمۡ حَرَجٗا مِّمَّا قَضَيۡتَ وَيُسَلِّمُواْ تَسۡلِيمٗا
English translation: But no by your Lord not will they believe until they make you judge about what arises between them then not they find in themselves any discomfort about what you (have) decided and submit (in full) submission
Transliteration: fala warabbika la yu'minuna hatta yuhakkimuka fima shajara baynahum thumma la yajidu fi anfusihim harajan mimma qadayta wayusallimu tasliman
