O men! serve your Lord Who created you and those before you so that you may guard (against evil). 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 of what We have revealed to Our votary, then bring a Surah like this, and call any witness, apart from God, you like, if you are truthful. 23 And if you cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones which awaits all who deny the truth! 24 But give glad tidings to those who believe and work righteousness, that their portion is Gardens, beneath which rivers flow. Every time they are fed with fruits therefrom, they say: "Why, this is what we were fed with before," for they are given things in similitude; and they have therein companions pure (and holy); and they abide therein (for ever). 25 ۞ Well, Allah is not ashamed to cite the similitude of a gnat or of something even more insignificant than this. As for those who believe, they come to know from the same similitude that it is the Revelation from their Lord; but those who disbelieve, say, "What does Allah mean by such similitudes?" Allah leads astray many and guides many to the right way by the same thing. And He leads astray only those who disobey Allah; 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 can you refuse to acknowledge God, seeing that you were lifeless and He gave you life, and that He will cause you to die and then will bring you again to life, whereupon unto Him you will be brought back? 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
