فَلا وَرَبِّكَ لا يُؤمِنونَ حَتّىٰ يُحَكِّموكَ فيما شَجَرَ بَينَهُم ثُمَّ لا يَجِدوا في أَنفُسِهِم حَرَجًا مِمّا قَضَيتَ وَيُسَلِّموا تَسليمًا

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.
