O you men, serve your Lord Who created you, and those that were before you; haply so you will be godfearing; 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 you be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 But if you do not do this, and you can never do this, then fear the Fire which has been prepared for the disbelievers and which shall have men and stones for fuel. 24 But unto those who have attained to faith and do good works give the glad tiding that theirs shall be gardens through which running waters flow. Whenever they are granted fruits therefrom as their appointed sustenance, they will say: "It is this that in days of yore was granted to us as our sustenance!" - for they shall be given something that will recall that [past]. And there shall they have spouses pure, and there shall they abide. 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 He it is Who created for you all that there is on the Earth; He then turned to the sky and ordered it into seven heavens. And He has full knowledge of everything. 29
