Taha 20:107

<h2>The destruction of the Mountains, and the Earth becomes a Smooth Plain</h2><p>Allah says, </p><div class="arabic uthmani">وَيَسْـَلُونَكَ عَنِ الْجِبَالِ</div><p>(And they ask you concerning the mountains.) This is a question, will they remain on the Day of Resurrection or will they cease to exist </p><div class="arabic uthmani">فَقُلْ يَنسِفُهَا رَبِّى نَسْفاً</div><p>(Say: "My Lord will blast them and scatter them as particles of dust.") This means that He will take them away from their places, wipe them out and remove them completely. </p><div class="arabic uthmani">فَيَذَرُهَا</div><p>(Then He shall leave it) referring to the earth; </p><div class="arabic uthmani">قَاعاً صَفْصَفاً</div><p>(as a level smooth plain.) This means one expanse spread out. The word Qa` means a piece of land that is level and the word Safsafa is used to place emphasis on this meaning. It has also been said that Safsafa means that which has no vegetation growing in it. The first meaning is preferred, even though the second meaning is also included by necessity. In reference to this, Allah says, </p><div class="arabic uthmani">لاَّ تَرَى فِيهَا عِوَجاً وَلا أَمْتاً </div><p>(You will see therein no crookedness nor curve. ) meaning, `on that Day you will not see in the earth any valley, hill, or any place, whether low or …

Wherein thou seest neither curve nor ruggedness.

"Nothing crooked or curved wilt thou see in their place."

"You will see therein nothing crooked or curved."

You will see in them neither crookedness, nor deviation.”
