Surah 84. Al-Inshiqaq, Ayah 1

I.e., at the coming of the Last Hour and the beginning of a new reality, both in fact and in man's perception.

The passing away of this world of sense to make way for a new World of Reality is here indicated by two Facts, which are themselves signs for a complete revolution in our whole knowledge and experience. At the beginning of S. lxxxii. and S. lxxxi, other Signs were used, to lead up to the arguments there advanced. Here the two Signs are: (1) the Sky being rent asunder and giving up its secrets, and (2) the Earth being flattened out from the globe it is, and giving up its secrets. See the following notes.
