Al-Kahf 47

وَيَوْمَ نُسَيِّرُ ٱلْجِبَالَ وَتَرَى ٱلْأَرْضَ بَارِزَةً وَحَشَرْنَٰهُمْ فَلَمْ نُغَادِرْ مِنْهُمْ أَحَدًا ﴿٤٧﴾

Wayawma nusayyiru aljibala watara alarda barizatan wahasharnahum falam nughadir minhum ahadan

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. The Noble Quran
