O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 21 Who hath made the earth for you a carpet and the heaven a structure, and sent down from heaven water, and brought forth therewith fruits as a Provision for you; wherefore set not up compeers unto Allah while ye know. 22 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true. 23 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 24 And give good news (O Muhammad), to those who believe in this Book and do good deeds (in accordance with its teachings). For them there will be gardens underneath which canals flow. Their fruits will so resemble the fruits on the Earth that every time they will be provided with fruits, they will say, "Such fruits were provided to us before on the Earth. " And there will be pure spouses for them and therein they will live for ever. 25 ۞ Lo! Allah disdaineth not to coin the similitude even of a gnat. Those who believe know that it is the truth from their Lord; but those who disbelieve say: What doth Allah wish (to teach) by such a similitude? He misleadeth many thereby, and He guideth many thereby; and He misleadeth thereby only miscreants; 26 who break their bond with God after it has been established [in their nature,] and cut asunder what God has bidden to be joined, and spread corruption on earth: these it is that shall be the losers. 27 What has made you disbelieve in Allah? Whereas you were dead and He gave you life; then He will give you death, then bring you to life again, and then it is to Him you will return! 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
