jesus didn't die, this's my beliefs.
In the An-Nisaa chapter in Quran, Allah Says:
"The people of the Scripture (Jews) ask you to cause a book to descend upon them from heaven. Indeed they asked Mûsa (Moses) for even greater than that, when they said: "Show us Allâh in public," but they were struck with thunder clap and lightning for their wickedness. Then they worshipped the calf even after clear proofs, vidences, and signs had come to them. (Even) so We forgave them. And We gave Mûsa (Moses) a clear proof of authority" [4:153]
"And for their covenant, We raised over them the Mount and (on the other occasion) We said: "Enter the gate prostrating (or bowing) with humility;" and We commanded them: "Transgress not (by doing worldly works on) the Sabbath (Saturday)." And We took from them a firm covenant" [4:154]
"Because of their breaking the covenant, and of their rejecting the Ayât (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allâh, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allâh has set a seal upon their hearts because of their disbelief, so they believe not buta little." [4:155]
"And because of their (Jews) disbelief and uttering against Maryam (Mary >Ç > ) a grave false charge (that she has committed illegal sexual intercourse);" [4:156]
"And because of their saying (in boast), "We killed Messiah 'Iesa (Jesus), son of Maryam (Mary), the Messenger of Allâh," - but they killed him not, nor crucified him, but the resemblance of 'Iesa (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. 'Iesa (Jesus), son of Maryam (Mary) >>>]:" [4:157]
"But Allâh raised him ['Iesa (Jesus)] up (with his body and soul) unto Himself (and he >> is in the heavens). And Allâh is Ever AllPowerful, AllWise." [4:158]
how can i - as a muslim- prove that Jesus didn't die?
simply because i belive that Quran is the words of Allah, and Allah doesn't tell lies,
it's "if-then" logic:
if quran is from allah then quran have no lies.
as for you -non-muslims- i have no historical or anthropological proofs that jesus died or not.
