Isa (AS), Quran and his second coming:

Re: Isa (AS), Quran and his second coming:

Peace kchughtai

Our understanding of “must believe in him” from verse 4:159 comes from "must believe in him as per the opposite of verse 5:116 - which is therefore

that he is a true prophet who neither

asked for worship of himself
nor for his mother.

Also, the statement that your rendition makes is already proven false … because many of the people of the book become Muslim every day.
