Translation of the verse 37 from Surah Ar-Rahman : Number of verses 78 - - page 532 - Part 27.
Then when the heaven is rent asunder, and it becomes rosy or red like red-oil, or red hide.
And when the heaven is split open and becomes rose-colored like oil -
(55:37) (What will happen) when the heaven will be split asunder and will become crimson like leather? *34
*34) This refers to the Day of Resurrection. Bursting of the heavens implies loosening of the discipline of the heavens, scattering of the celestial bodies, upsetting of the system of the heavens. And the meaning of `reddening like red leather" is that during that great upheaval anyone who looks up towards the sky, will feel as though the entire heavens were on fire.
