On the day when the earth with all its mountains will be in a violent commotion, and the mountains will crumble into heaps of shifting sand
Dr. Munir Munshey
(Let them be) then, till that day when the earth and the mountains would rock and reel violently. The mountains would turn into heaps of loosely packed sand
Dr. Kamal Omar
The Day the earth and the mountains shake violently, and the mountains became a heap of sand crumbling down
(They will come across all this) on the Day when the earth and the mountains shall tremble violently and the mountains shall crumble into heaps of scattered sand
Ali Bakhtiari Nejad
on a day that the earth and the mountains shake and the mountains become a pile of flowing sands
At that time the earth (body) and the mountains (ego-identities) will be shaken... And the mountains will become a heap of dust!
Al-muntakhab fi tafsir al-Qur'an al-Karim
One Day the earth and the mountains shall be thrown into earthquakes, volcanoes and convulsions, and the mountains cave in and become like wind- drifted sand
