اقرأ وتدبر الآية 652 من سورة سُورَةُ النِّسَاءِ: وَإِنْ مِنْ أَهْلِ الْكِتَابِ إِلَّا لَيُؤْمِنَنَّ بِهِ قَبْلَ مَوْتِهِ ۖ وَيَوْمَ الْقِيَامَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا
وَإِنْ مِنْ أَهْلِ الْكِتَابِ إِلَّا لَيُؤْمِنَنَّ بِهِ قَبْلَ مَوْتِهِ ۖ وَيَوْمَ الْقِيَامَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا
Yet there is not one of the followers of earlier revelation who does not, at the moment of his death, grasp the truth about Jesus; and on the Day of Resurrection he [himself] shall bear witness to the truth against them.
