You will not see therein a depression or an elevation." (20:107)

Almuntakhab Fi Tafsir Alquran Alkarim

Wherefore you cannot see curves, elevations nor depressions

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(20:107) wherein you will neither see any curve nor crease. " *83

You will not see therein a depression or an elevation." meaning

*83) According to the Qur'an, the earth will take a new shape in the Hereafter:
"The earth will be spread." (LXXXIV: 3).
"The bottoms of the oceans will be split (and the whole water will sink down in the earth.)" (LXXXII: 3).
"The oceans will be filled up". (LXXXI: 6).
"The mountains will be reduced to fine dust and scattered away and there will be left no curve or crease in the earth". (XX: 105-107).
"On that day the earth will be totally changed". (XIV: 48).
"And it will be turned into a garden and given to the pious people to dwell therein for ever." (XXXIX: 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. Hadrat Ibn 'Abbas and Qatadah have held this same view that Paradise will be established on this very earth.
