النساۤء — An-Nisa' Ayat 159
وَاِنْ مِّنْ اَهْلِ الْكِتٰبِ اِلَّا لَيُؤْمِنَنَّ بِهٖ قَبْلَ مَوْتِهٖ ۚوَيَوْمَ الْقِيٰمَةِ يَكُوْنُ عَلَيْهِمْ شَهِيْدًاۚ
Wa im min ahlil-kitābi illā layu'minanna bihī qabla mautih(ī), wa yaumal-qiyāmati yakūnu ‘alaihim syahīdā(n).
"And there is none from the People of the Scripture but that he will surely believe in Jesus before his death. And on the Day of Resurrection he will be against them a witness."
