(2) And if ye are in doubt concerning that which We reveal unto Our slave (Muhammad), then produce a surah of the like thereof, and call your witness beside Allah if ye are truthful.

(3) And give glad tidings (O Muhammad) unto those who believe and do good works; that theirs are Gardens underneath which rivers flow; as often as they are regaled with food of the fruit thereof, they say: this is what was given us aforetime; and it is given to them in resemblance. There for them are pure companions; there for ever they abide.

(4) Those who break the covenant of Allah after ratifying it, and sever that which Allah ordered to be joined, and (who) make mischief in the earth: Those are they who are the losers.

(5) And when thy Lord said unto the angels: Lo! I am about to place a viceroy in the earth, they said: Wilt thou place therein one who will do harm therein and will shed blood, while we, we hymn Thy praise and sanctify Thee? He said: Surely I know that which ye know not.

(6) They said: Be glorified! We have no knowledge saving that which Thou hast taught us. Lo! Thou, only Thou, art the Knower, the Wise.

(7) He said: O Adam! Inform them of their names, and when he had informed them of their names, He said: Did I not tell you that I know the secret of the heavens and the earth? And I know that which ye disclose and which ye hide.

(8) But Satan caused them to deflect therefrom and expelled them from the (happy) state in which they were; and We said: Fall down, one of you a foe unto the other! There shall be for you on earth a habitation and provision for a time.

(9) And believe in that which I reveal, confirming that which ye possess already (of the Scripture), and be not first to disbelieve therein, and part not with My revelations for a trifling price, and keep your duty unto Me.

(10) And when We said: Go into this township and eat freely of that which is therein, and enter the gate prostrate, and say: "Repentance." We will forgive you your sins and will increase (reward) for the right-doers.
