(Al-Kahf) 18 : 8
وَإِنَّا لَجَاعِلُونَ مَا عَلَيْهَا صَعِيدًا جُرُزًا
And indeed, We will make this earth a barren ground.
When Trumpet for the Doomsday is blown, the earth will be leveled by pounding and crushing as explained in verses 14: 48. It is told in verses 27: 87-88: “On the Day when Trumpet will be blown, whoever is in the heavens and whoever is on the earth will be terrified except whom Allah wishes; and all will come to Lord submissive. And you see the mountains as rigid now, and they will pass like the clouds, that is Production of Allah who perfected all things; indeed He is acquainted with whatever you are doing”. It is told in verse 101: 5 that mountains will be like fluffed up wool. It is told in verse 78: 20 that the mountains are removed and will be like a mirage. See explanation 1: 3.
