4:159

An-Nisaa 4:159

وَإِن مِّنْ أَهْلِ ٱلْكِتَٰبِ إِلَّا لَيُؤْمِنَنَّ بِهِۦ قَبْلَ مَوْتِهِۦ ۖ وَيَوْمَ ٱلْقِيَٰمَةِ يَكُونُ عَلَيْهِمْ شَهِيدًۭا

Wa im min Ahlil Kitaabi illaa layu'minanna bihee qabla mawtihee wa Yawmal Qiyaamati yakoonu 'alaihim shaheedaa

And there is not one of the followers of the Book but most certainly believes in this before his death, and on the day of resurrection he (Isa) shall be a witness against them.
