83. According to the Quran, the earth will take a new shape in the Hereafter:

The earth will be spread. (Surah Al-Inshiqaq, Ayat 3).

The bottoms of the oceans will be split (and the whole water will sink down in the earth). (Surah Al-Infitar, Ayat 3).

The oceans will be filled up. (Surah At-Takweer, Ayat 6).

The mountains will be reduced to fine dust and scattered away and there will be left no curve or crease in the earth. (Surah Taaha, Ayats 105-107).

On that day the earth will be totally changed. (Surah Ibrahim, Ayat 48).

And it will be turned into a garden and given to the pious people to dwell therein forever. (Surah Az-Zumur, Ayat 74).

This shows that ultimately this earth will be turned into Paradise which will be inherited by the pious and righteous servants of Allah. The whole earth will become one country, and there will be no mountains, oceans, rivers and deserts which today divide it into countless countries and homelands and divide mankind as well into as many tribes, races and classes. Ibn Abbas and Qatadah have the same view that Paradise will be established on this very earth.
