O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 21 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. 22 If you are in doubt about the revelation We have sent down to Our servant, then produce a single chapter like it, and call upon your helpers besides God, if you are truthful. 23 If you do not produce such a chapter and you never will then guard yourselves against the fire whose fuel will be people and stones and is prepared for those who hide the Truth. 24 Bear glad tidings to those who believe and do good works. They shall live in Gardens underneath which rivers flow. Whenever they are given fruit as provision they will say: 'This is what we were given before,' for they shall be given in resemblance. Therein they shall have pure spouses, and shall live there for ever. 25 ۞ Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors, 26 Who break the covenant of Allah after contracting it and sever that which Allah has ordered to be joined and cause corruption on earth. It is those who are the losers. 27 How is it that you adopt the attitude of disbelief towards Allah when the fact is that you were lifeless and He gave you life, and He will take away life from you and will again restore you to life: then you shall ultimately return to Him. 28 He it is who has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
