﴿You do not see﴾ meaning by sight [and] not by insight ﴿in it﴾ meaning the locations of the mountains ﴿crookedness﴾ in one of the ways. He expressed this with a kasra, which is for meanings, and did not express it with a fatha, which is used for entities. The locations of the mountains are entities, not meanings, negating crookedness in the most eloquent way, meaning that if you gathered the people of expertise regarding the leveling of the lands, they would agree on the ruling of its flatness. Then, if you gathered the people of engineering and they applied their scientific measures to it, they would rule similarly. ﴿And no elevation﴾ meaning anything elevated like a hillock or a slight rise or a crack [or difference]; and Al-Baydawi and Al-Zamakhshari said: the elevation is the slight rise. Al-Ghazali said in Al-Durra Al-Fakhira: (p-346) the trumpet will be blown, and the mountains will fly away, and the rivers will burst forth into one another, so the realm of the air will be filled [with water], and the stars will scatter and the sky and the earth will change, and the inhabitants will die, so the earth and the sky will be empty. He said: then He, glorified and exalted is He, will uncover a house in Saqar, and the flames of the fire will emerge, igniting in the seas, causing them to dry up, and leaving the earth a black ember, and the heavens as if they were murky oil and molten copper. Then, the Most High will open a treasury from the treasures of the Throne in which is the sea of life, and He will rain it upon the earth, like the sperm of men, so the bodies will grow in their form, the child will be a child, and the old man will be an old man, and what is between them. Then, a gentle fire will blow from beneath the Throne, and the earth will emerge with no mountain, no crookedness, and no elevation. Then Allah will revive Israfil, and he will blow into the trumpet from the rock of Al-Quds, and the souls will exit from a hole in the trumpet, each soul to its body, even the wild animals and the birds, and they will be at Al-Sahira.
