How is the Day of Judgement described in the Qur'an?

As stated in the Qur’an, “… The Hour is coming…” (Surah Ta Ha, 15). On that day all living things, along with the stars, planets and galaxies, in short, everything in the heavens and the earth will vanish. Some of the occurrences that are due to take place are depicted in the Qur’an as follows:

Heaven will be split apart, for that Day it will be very frail. (Surat al-Haqqa, 16)

The stars will fall in rapid succession. (Surat at-Takwir, 2)

The sun and moon will be fused together. (Surat al-Qiyama, 9)

The oceans will surge into each other. (Surat at-Takwir, 6)

The mountains will become like shifting dunes. (Surat al-Muzzammil, 14)

The mountains will be like tufts of coloured wool. (Surat al-Qari’a, 5)

The earth will be crushed and ground to dust. (Surat al-Fajr, 21)

The earth will disgorge its charges. (Surat az- Zilzal , 2)

These are only a few of the terrifying happenings that will occur on the Day of Judgement. On that day, essentially everything that man values will vanish, and everyone will understand that nothing, other than the right actions done for the pleasure of Allah, is of any value.
