I very much doubt that the opportunity will ever present it self except in the presence of utmost secrecy.
If the Muslims get any hint that they are attempting to perform this sacrifice they will commit untold atrocities to prevent it.
In the 600s, the Persian Sassanian dynasty conquered Jerusalem with the help of Jews.
He handed it over to them and Nehemiah, the leader, began plans to build a third temple. He didn’t complete it as the Byzantines won shortly later.
Also, when the Arabs conquered Jerusalem, they did so with Jewish help and gave control of the city to Jews to control (under Arab control).
One very interesting side-note from Robert Spencer: if you look at the inside of the Dome of the Rock, it has the Shahadah (the Mohammedan allegiance statement that is basically “La illah allah, muhammad al rasurillah, shadwan al rasurillah” - “there is no god but Al, Mo is his profit”.
BUT, the writing is NOT the same as this - it is changed, and that should be extreme blasphemy. But it is written on the inside of a “holy place” — anyway the upshot is that the Arabs who conquered the Sassanid empire and much of the Roman Empire in Asia and Africa, they were descendents of the Lakhamid and Ghassanid Arab mercenaries that had been fighting for the Romans and Persians for nearly 3 centuries and hadn’t been getting paid in the last few decades.
They were followers of a “kind of Christianity” - Gnostic mixed with heavy Judaizing. But it hadn’t settled and didn’t have a “prophet”. That all came 150 odd years after their conquests, when the Ummayyads were replaced by Fatimids.
