وَإِن مِّنْ أَهْلِ ٱلْكِتَـٰبِ إِلَّا لَيُؤْمِنَنَّ بِهِۦ قَبْلَ مَوْتِهِۦ ۖ وَيَوْمَ ٱلْقِيَـٰمَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا
wa-in min ahli l-kitābi illā layu'minanna bihi qabla mawtihi wayawma l-qiyāmati yakūnu ʿalayhim shahīdan
And there is none from the People of the Scripture but that he will surely believe in him [i.e., Jesus] before his death. And on the Day of Resurrection he will be against them a witness.
