The Arabic word Taghabun (great loss or deprivation) comes from the word Ghabn, which means loss when buying or selling, or selling someone short. The Day of Resurrection is called Yawm At-Taghabun because of what will become apparent on that day of the loss of those who followed disbelief and misguidance, for they have sold their Hereafter for the sake of worldly gain. So their loss will become apparent and whatever profit they made will perish.

What the verse means is that the sun cannot rise at night, because the night is the time for the moon to rise, and the moon cannot rise during the day, because that is the time for the sun to rise. Solar and lunar eclipses do not come under the heading of the catching up that is referred to in the verse.

Islam is the only religion in the sight of Allah. It is the religion that was revealed to all of the prophets, including Abraham, Moses, Jesus, and Muhammad. Islam is based on the belief in Allah, and the submission to His will.
