Thank you very much for exposing yourself. That's what Mirza Ghulam Ahmad claimed to be Messiah and Mehdi (Naúzubillah) and what not??? He tried to distort also the Quranic verses according to his choice and gain.
There is a clear cut verse in Quran regarding this:
Verse 157: Surra Alnisa(4) part 6: And because of their saying (in boast), "We killed Messiah Ïsa(jesus), son of Mariam, the messenger of Allah."-- but they killed him not, nor they crusified him, but the resemblace of Isa was put over another man ( and they killed that man) and those that differ there in are full of boubts. They have no knowledge, they follow nothing but conjecture. For surely they killed him not.
Now in the above Ayat, where it is written that he was even taken on the Cross?? It is clearly mentioned that they have crusified his resembler.
It did not say a resemble was crucified it said the act of his crucifixion was a resmblance to them. Its the "them" we should also look at as the Quran was clearly talking to the Jews. The translation you have is a fudge.
4.157. That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of God.;- but they killed him not, nor crucified him, but so it was made to appear to** them*, and **those* who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not:-
As far as the Ahmadis to say that if you don't believ in the finality of some prophet means kufr is not correct Quranically since this has no bearing to your faith in God or His message. The Sunni and Shia clerics fear someone would then come and say he is a prophet or something plus it was Maudoodi who lobbied hard the Pakistani government probably with the help of the Saudis. Today we see where Maudoodi and the Saudis have taken us. To the Taliban!
If your grandma have passed away and then brought back to life two or three days later some people would say "she never died but she is alive"! Meaning as of now. Other would say "grandma died but was brought back to life!" Meaning from the past till now. Its a question of timing reference. But the verse was clearly countering the Talmudic claim about Jesus and Mary and was directed towards that crowd. The jewish Talmud never mentions the Romans and does not believe Jesus was a Messiah and does not even believe he was resurrected. they thought he died and they believed they killed them but there is a difference among the Rabbis as to what actually happened and who Jesus really was.
