O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 Worship God who has rendered the earth as a floor for you and the sky as a dome for you and has sent water down from the sky to produce fruits for your sustenance. Do not knowingly set up anything as an equal to God. 22 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. 23 And if ye do it not - and ye can never do it - then guard yourselves against the Fire prepared for disbelievers, whose fuel is of men and stones. 24 Give the good news to those who believe and do good works, that they will have Gardens through which rivers flow: whenever they are given fruit to eat they will say, "This is what we were provided with before," because they were given similar things. And there will be pure spouses for them, and they will abide there forever. 25 ۞ Indeed Allah does not, for the sake of explanation, shy to illustrate an example of anything, whether it is of a gnat or something further (inferior) than it; so the believers know it is the Truth from their Lord; as for the disbelievers, they say, “What does Allah intend by such an example?” He misleads many thereby, and He guides many thereby; and with it He misleads only those who are rebellious. 26 those who break God's covenant after they have pledged to keep it, and sever whatever God has ordered to be joined, and spread corruption in the land -- it is they who are the losers. 27 How do you disbelieve in God, seeing you were dead and He gave you life, then He shall make you dead, then He shall give you life, then unto Him you shall be returned? 28 He it is Who created for you all that is in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
