This man is ignorant and he may be in great danger as what he believes in can be an act of apostasy.

Believing that Isa alaihi salam is dead contraditcs the Qur’an and brings that one out of islam.
“And because of their saying (in boast), ‘We killed the Messiah ‘Eesa (Jesus), son of Maryam (Mary), the Messenger of Allaah,’ — but they killed him not, nor crucified him, but it appeared so to them the resemblance of ‘Eesa (Jesus) was put over another man (and they killed that man)], and those who differ therein are full of doubts. They have no (certain) knowledge, they follow nothing but conjecture. For surely; they killed him not [i.e. ‘Eesa (Jesus), son of Maryam (Mary)]:

But Allaah raised him [‘Eesa (Jesus)] up (with his body and soul) unto Himself (and he is in the heavens). And Allaah is Ever All Powerful, All Wise”[al-Nisaa’ 4:157-158]

The surah he ref was 23:50: I had debate with a person that is a muslim, about the Prophet Jesus AWS that he’s not dead , but he says the prophet Jesus AWS is dead as the book with title” Jesus dead. ” by mullahs hafiz
