Sorry, I thought you believed in the substitution theory conventionally adopted by the mainstream Islam. Does your denial of the substitiution theory mean that YOU also believe Jesus was crucified? If you believe this, you go against the Koran, which fails to support its claims about the cross through a narrative, yet explicitly rejects that Jesus was crucified:
4: 157. And because of their saying: We slew the Messiah, Jesus son of Mary, Allah’s messenger - they slew him not nor crucified him, but it appeared so unto them.
.
Where do you read in the Koran that Jesus was crucified, but He survived death since His legs were not broken? Where do you read in the Gospels that Jesus surived death without the need of a miracle? You seem to be combining some parts of the Koran with some parts of the Gospel narratives in order to prove your personal comments that contradict both of your sources.
I m totally lost at this point.

You say that Jesus was crucified, but He did not die there??? Why did not Allah save His beloved Jesus from crucifixion then? Why did He wait until Jesus came to the verge of death? Why did Allah let Jesus/Issa suffer on the cross? Death was the peak of Jesus’ passion. His adversaries did not want to kill Him immediately, but desired to see Him crucified and suffer for long hours According to your interpretation, they managed to do that! Where is the victory then? .
The Muslims I have questioned on this issue support the substitution theory through the following verses:
3: 54. And they (the disbelievers) schemed, and Allah schemed (against them): and Allah is the best of schemers.
5: 110. When Allah saith: O Jesus, son of Mary! Remember My favour unto thee and unto thy mother … how I restrained the Children of Israel from (harming) thee when thou camest unto them with clear proofs.
Thanks and peace,
