Surah 52. At-Tur, Ayah 6

I.e., "Consider the immensity and wonderful configuration of the visible universe as an evidence of a conscious Creator."

 The seas and oceans will be on fire on Judgment Day.

(5) The Ocean-the vast, limitless, all encircling Ocean. It is expressed to be masjur, full of a mighty swell, boiling over, poured forth all over the earth, as if overwhelming all landmarks; Cf. lxxxi. 6: a fitting description of the final disappearance of our temporal world in the supreme establishment of the judgment.

This completes the five Signs by which man may know for certain of the Judgment to come. Note that they are in a descending order: the highest, or most remote from man's consciousness, being mentioned first, and that nearest to man's consciousness being mentioned last. The truth of Revelation; its embodiment in a Prophet's Message given in human language; the universal appeal of divine worship; the starry world above; and the encircling Ocean, full of life and motion below,-all are evidences that the Day of Allah will finally come, and nothing can avert it.
