Every one of the People of the Book will definitely believe in him before his death.¹ And on the Day of Judgment Jesus will be a witness against them.

And there is none of the people of the Scripture (Jews and Christians) but must believe in him [‘Îsâ (Jesus), son of Maryam (Mary), as only a Messenger of Allâh and a human being]¹ before his [‘Îsâ (Jesus) عليه السلام) or a Jew’s or a Christian’s] death² (at the time of the appearance of the angel of death). And on the Day of Resurrection, he [‘Îsâ (Jesus)] will be a witness against them.
