[Quranic Reflection]: moon absorbed by the sun in the Quran: far future.

[WinterHold]

When the sun becomes a red giant, automatically the light from the moon will be dimmed because the light from the sun will be massive + both the earth and the moon will be so close from the sun. So massive that a celestial body that reflects the sun's light will be insignificant.

The distance of the moon from earth is ever-increasing, so it's going to be getting dimmer for quite a while, by the time the sun becomes a red giant its orbit will be about 40% larger that it is today. When the sun is a red giant the drag caused by its extended atmosphere will cause the moon's orbit to decay, drawing it closer to earth (and therefore becoming brighter). When the moon reaches the Roche Limit, tidal forces will pull it apart, forming a Saturn-like ring over the equator. The debris will eventually fall to earth and the planet will be moonless by the time the sun reaches its greatest point of expansion, which may or may not include the earth.

So the debris of the moon will fall into earth, then both will fall into the sun, that means that the sun and the moon did join..at that point the humans present on earth would say:

(10) on that Day one will cry, “Where is the escape?”-Sura 75, The Quran: 

Note that all of this would happen on judgement day which is "the day of resurrection", humans will be resurrected from death with stronger bodies that can sustain very long duration of hellish suffering or eternal joy in paradise.
