I have read the Koran in three English translations. Jerusalem is never mentioned in the Koran.
You seem to be conflating two holy sites. There is the Temple of Jerusalem, where the Dome of the Rock is, and there is the burial site of Jesus.
Christians worshiped at the burial site of Jesus until Emperor Hadrian built a temple to Venus there. Constantine's mother had the temple to Venus torn down, and The Church of the Holy Sepulcher was built there instead. The Church f the Holy Sepulcher is still there. Years ago, I read an article in the Biblical Archaeology Review that said that the Church of the Holy Sepulcher probably is the burial site of Jesus.
Protestant Fundamentalists think the Garden Tomb is the burial site of Jesus. The article said that Biblical archaeologists think it is an older burial site.
The history you are relating is not in line with what I'm remembering learning years ago.
Wildly divergent.
Where yes, Constantine was not exactly the guy the Catholics make him out to be he is not the evil guy the 7th Day Adventist make him out to be either....nor was He or his family who the Muslims make him out to be either.
Which is a massive problem. Everyone tells the story differently with a goal of achieving desired modern results. The truth is no longer relevant and instead only individual opinions matter any longer. And THAT is the problem in Israel. Why the riots at the Tomb of the Holy Sepulcher happen, why the Muslims and Jews fight, why the Christians fight the Muslims and Jews. (And if the Palestinians hadn't run off the Christians they might actually have a REAL friend in their current fight....but they are bloodthirsty savages at this point.)
The Palestinians are NOT a solution to the Dome of the Rock issue. What? You think that they, after 80 years of being insurgents in the WHOLE Middle East they are going to suddenly become peaceful, industrious, and create economic opportunities for everyone?
Yeah....that's never going to happen.
If the Jews gain it....it will be like any of their other lands. The Christians won't fight the Jews....they much prefer infighting...just like the Jews.
BTW....
Mary, the Mother of Jesus, was Jewish, not Muslim.She was born in Herodian Judea, not Palestine.She raised Her Son in Galilee, not Jund al-Urdunn.She spoke Galilean Aramaic and Hebrew, not Arabic.During the Crucifixion, she was in Jerusalem, not Al-Quds
