(591) And when (his son) was old enough to walk with him, (Abraham) said: O my dear son, I have seen in a dream that I must sacrifice thee. So look, what thinkest thou? He said: O my father! Do that which thou art commanded. Allah willing, thou shalt find me of the steadfast.

(592) Glorified be Allah from that which they attribute (unto Him),

(593) Lo! verily, ye and that which ye worship,

(594) Glorified be thy Lord, the Lord of Majesty, from that which they attribute (unto Him)

(595) Lo! this in truth is Our provision, which will never waste away.

(596) He said: O Iblis! What hindereth thee from falling prostrate before that which I have created with both My hands? Art thou too proud or art thou of the high exalted?

(597) If Allah had willed to choose a son, He could have chosen what He would of that which He hath created. Be He Glorified! He is Allah, the One, the Absolute.

(598) And when some hurt toucheth man, he crieth unto his Lord, turning unto Him (repentant). Then, when He granteth him a boon from Him he forgetteth that for which he cried unto Him before, and setteth up rivals to Allah that he may beguile (men) from his way. Say (O Muhammad, unto such an one): Take pleasure in thy disbelief a while. Lo! thou art of the owners of the Fire.

(599) But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not His promise.

(600) Allah receiveth (men's) souls at the time of their death, and that (soul) which dieth not (yet) in its sleep. He keepeth that (soul) for which He hath ordained death and dismisseth the rest till an appointed term. Lo! herein verily are portents for people who take thought.
