Surah 101. Al-Qariah, Ayah 1

I.e., the coming of the Last Hour, which will involve a terrifying transformation of the world (see note [63] on 14:48 and note [90] on {20:105-107}).

The Day of Noise and Clamour is the Day of Judgment, when the whole of the present order of things will be overthrown with a tremendous convulsion. Cf. n. 6235 to xcix. 1, and n. 6096 to lxxxviii. All our present landmarks will be lost. It will be a stunning experience to begin with, but it will inaugurate a new world of true and permanent values, in which every human deed will have its true and just consequences, as if weighed in the balance. See verses 6-11 below.
