O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth). 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 do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers. 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 Those who break Allah's Covenant after it is ratified, and who sunder what Allah Has ordered to be joined, and do mischief on earth: These cause loss (only) to themselves. 27 How disbelieve ye in Allah when ye were dead and He gave life to you! Then He will give you death, then life again, and then unto Him ye will return. 28 It is He who created everything on the earth for you: then He turned towards heaven and fashioned it into the seven heavens. He has knowledge of all things. 29
