Allah says,
[وَيَسْـَلُونَكَ
عَنِ الْجِبَالِ]
(And they ask you concerning the mountains.) This is a question, will they
remain on the Day of Resurrection or will they cease to exist
[فَقُلْ يَنسِفُهَا
رَبِّى نَسْفاً]
(Say: "My Lord will blast them and scatter them as particles of dust.'') This
means that He will take them away from their places, wipe them out and remove
them completely.
[فَيَذَرُهَا]
(Then He shall leave it) referring to the earth;
[قَاعاً
صَفْصَفاً]
(as a level smooth plain.) This means one expanse spread out. The word Qa`
means a piece of land that is level and the word Safsafa is used to place
emphasis on this meaning. It has also been said that Safsafa means that which
has no vegetation growing in it. The first meaning is preferred, even though the
second meaning is also included by necessity. In reference to this, Allah says,
[لاَّ تَرَى فِيهَا
عِوَجاً وَلا أَمْتاً ]
(You will see therein no crookedness nor curve. ) meaning, `on that Day you
will not see in the earth any valley, hill, or any place, whether low or
elevated.' Ibn `Abbas, `Ikrimah, Mujahid, Al-Hasan Al-Basri, Ad-Dahhak, Qatadah
and others of the Salaf all said the same.
