Qur'ān 18:47 · Al-Kahf (الكهف)

وَيَوْمَ نُسَيِّرُ ٱلْجِبَالَ وَتَرَى ٱلْأَرْضَ بَارِزَةًۭ وَحَشَرْنَـٰهُمْ فَلَمْ نُغَادِرْ مِنْهُمْ أَحَدًۭا

And [warn of] the Day when We will remove the mountains and you will see the earth prominent, and We will gather them and not leave behind from them anyone.
