وَيَوْمَ نُسَيِّرُ الْجِبَالَ وَتَرَى الْأَرْضَ بَارِزَةً وَحَشَرْنَاهُمْ فَلَمْ نُغَادِرْ مِنْهُمْ أَحَدًا
[18:47]
And the day on which We will cause the mountains to pass away and you will see the earth a levelled plain and We will gather them and leave not any 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 (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.
