Al-Kahf 18:47

<h2>The Major Terrors of the Hour</h2><p>Allah tells us of the terrors of the Day of Resurrection, and the awesome things that will come to pass, as He says elsewhere:</p><p>يَوْمَ تَمُورُ السَّمَآءُ مَوْراً - وَتَسِيرُ الْجِبَالُ سَيْراً</p><p>(On the Day when the heaven will shake with a dreadful shaking, And the mountains pass moving away.) 52:9-10 meaning, they will move from their places and will vanish. As Allah says:</p><p>وَتَرَى الْجِبَالَ تَحْسَبُهَا جَامِدَةً وَهِىَ تَمُرُّ مَرَّ السَّحَابِ</p><p>(And you will see the mountains and think them solid, but they shall pass away as the passing away of the clouds.) 27:88</p><p>وَتَكُونُ الْجِبَالُ كَالْعِهْنِ الْمَنفُوشِ</p><p>(And the mountains will be like carded wool.) 101:5</p><p>وَيَسْـَلُونَكَ عَنِ الْجِبَالِ فَقُلْ يَنسِفُهَا رَبِّى نَسْفاً - فَيَذَرُهَا قَاعاً صَفْصَفاً - لاَّ تَرَى فِيهَا عِوَجاً وَلا أَمْتاً</p><p>(And they ask you about the mountains, say: "My Lord will pulverize them scattering their dust.

So Allah says:</p><p>وَتَرَى الاٌّرْضَ بَارِزَةً</p><p>(and you will …

And (bethink you of) the Day when we remove the hills and ye see the earth emerging, and We gather them together so as to leave not one of them behind.

One Day We shall remove the mountains, and thou wilt see the earth as a level stretch, and We shall gather them, all together, nor shall We leave out any one of them.

And (remember) the Day We shall cause the mountains to pass away (like clouds of dust), and you will see the earth as a levelled plain, and we shall gather them all together so as to leave not one of them behind.

On the Day when We set the mountains in motion; and you see the earth emerging; and We gather them together, and leave none of them behind.
