(212) And how many angels are in the heavens whose intercession availeth naught save after Allah giveth leave to whom He chooseth and accepteth.

(213) And unto Allah belongeth whatsoever is in the heavens and whatsoever is in the earth, that He may reward those who do evil with that which they have done, and reward those who do good with goodness.

(214) Then opened We the gates of heaven with pouring water

(215) All that are in the heavens and the earth entreat Him. Every day He exerciseth (universal) power.

(216) O company of jinn and men, if ye have power to penetrate (all) regions of the heavens and the earth, then penetrate (them)! Ye will never penetrate them save with (Our) sanction.

(217) And when the heaven splitteth asunder and becometh rosy like red hide -

(218) All that is in the heavens and the earth glorifieth Allah; and He is the Mighty, the Wise.

(219) His is the Sovereignty of the heavens and the earth; He quickeneth and He giveth death; and He is Able to do all things.

(220) He it is Who created the heavens and the earth in six Days; then He mounted the Throne. He knoweth all that entereth the earth and all that emergeth therefrom and all that cometh down from the sky and all that ascendeth therein; and He is with you wheresoever ye may be. And Allah is Seer of what ye do.
