4:65
فَلَا وَرَبِّكَ لَا يُؤْمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيْنَهُمْ ثُمَّ لَا يَجِدُوا۟ فِىٓ أَنفُسِهِمْ حَرَجًا مِّمَّا قَضَيْتَ وَيُسَلِّمُوا۟ تَسْلِيمًا
falā warabbika lā yu'minūna ḥattā yuḥakkimūka fīmā shajara baynahum thumma lā yajidū fī anfusihim ḥarajan mimmā qaḍayta wayusallimū taslīman
By your Lord, they will not be true believers until they let you decide between them in all matters of dispute, and find no resistance in their souls to your decisions, accepting them totally-
But no, by your Lord, they can have no Faith, until they make you (O Muhammad صلى الله عليه وسلم) judge in all disputes between them, and find in themselves no resistance against your decisions, and accept (them) with full submission.
