Verse 4:159

وَإِن مِّنْ أَهْلِ ٱلْكِتَـٰبِ إِلَّا لَيُؤْمِنَنَّ بِهِۦ قَبْلَ مَوْتِهِۦ ۖ وَيَوْمَ ٱلْقِيَـٰمَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا

“There is none among the People of the Book but will surely believe in him before his death; and on the Day of Resurrection he will be a witness against them”
