On that Day, a cloud will appear rending the sky and the angels will be senthi down rank after rank.

(What will happen) when the heaven will be split asunder and will become crimson like leather?

when the sky will be rent asunder, the grip holding it together having loosened on that Day,

the Day whose severity shall cause the heaven to split asunder? Allah's promise is ever bound to be fulfilled.

and the sky is rent asunder,

and when the sky shall be opened up and will become all doors;

and when Heaven is laid bare;

When the heaven is split asunder,

When the sky is rent asunder

and hearkens to the command of its Lord, doing what it should;
