Verily, This is the Word that separates...

So let man see from what he is created!

He is created from a water gushing forth

Proceeding from between the back-bone and the ribs,

Verily, (Allah) is Able to bring him back (to life)!

The Day when all the secrets (deeds, prayers, fasting, etc.) will be examined (as to their truth).

Then will (man) have no power, nor any helper.

By the sky (having rain clouds) which gives rain, again and again.

And the earth which splits (with the growth of trees and plants),

Verily! This (the Qur'an) is the Word that separates (the truth from falsehood, and commands strict legal 

laws for mankind to cut the roots of evil).

And it is not a thing for amusement.

Surah at-Tariq [86:5-14]
