Paradise is often mentioned in the Quran, but heavenly blessings are linked to a very specific action only once: “If they had followed the Torah and the Gospel and what was sent down to them from their LORD, they would indeed have eaten from what is above them and at their feet” (V 66).
There is a comparable passage in the Bible: “You expect much, but behold, it turns out to be little; and even when you bring it home, I blow it away. Why is this? says the LORD of Hosts. Because my house lies in ruins, while each of you is busy tending to your own house. Therefore, the heavens above you have withheld the dew, and the earth has withheld its produce. And I have called for a drought on the land and the mountains, on the grain, the new wine, the oil, and on everything that comes from the ground, as well as on people and livestock and on all the work of human hands.” (Hag. 1:9–11)
“…truly, then they would have eaten what is above them and at their feet…” <=> “…therefore the heavens above you have withheld the dew, and the earth has withheld its produce…”,
This is a very similar description of heavenly blessing. And I believe there are no comparable passages for such a blessing.
Another passage shows just how important the Temple of Israel is for the future salvation of us all. The rebuilding of the Temple is also linked to the moment when “swords” are turned back into “plowshares”—that is, when the peace we all so long for will come: “In the days to come, it will happen: The mountain of the Lord’s house / is firmly established as the highest of the mountains; it towers above all the hills. / All peoples will stream to it. Many nations will set out on their journey. / They will say: ‘Come, let us go up to the mountain of the Lord / and to the house of the God of Jacob. He will teach us his ways, / and we will walk in his paths.’ For from Zion comes the Lord’s instruction, / and from Jerusalem his word. He will judge between the nations / and settle disputes for many peoples. Then they will beat their swords into plowshares / and their spears into pruning hooks. Nation will no longer lift up sword against nation, / nor will they train for war.” (Isa. 2:2–4; cf. Mic. 4:1–3).
But how could this be achieved, in full accordance with the words of Zechariah: “Not by might, nor by power, but by My Spirit, says the LORD” (Zech. 4:6), when Muslims are the masters of the Temple Mount? In this regard, too, a unified interpretation of the Hebrew Bible, the Gospel, and the Quran would be decisive, for Muslims would have to agree to it.
By the way: GOD says through Jesus that He will rebuild the temple three days after it is destroyed (John 2:19). One day with GOD is equal to a thousand of our years (Psalm 90:4; Quran: XXII 47), and the third millennium has just begun.
