O you men, serve your Lord Who created you, and those that were before you; haply so you will be godfearing; 21 who assigned to you the earth for a couch, and heaven for an edifice, and sent down out of heaven water, wherewith He brought forth fruits for your provision; so set not up compeers to God wittingly. 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 ye do it not, and by no means ye shall, then dread the Fire, the fuel whereof is men and stones, gotten ready for the infidels. 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 ۞ Verily, Allah is not ashamed to set forth a parable even of a mosquito or so much more when it is bigger (or less when it is smaller) than it. And as for those who believe, they know that it is the Truth from their Lord, but as for those who disbelieve, they say: "What did Allah intend by this parable?" By it He misleads many, and many He guides thereby. And He misleads thereby only those who are Al-Fasiqun (the rebellious, disobedient to Allah). 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 How do you deny Allah and you were dead and He gave you life? Again He will cause you to die and again bring you to life; then you shall be brought back to Him. 28 He it is Who created for you all that is in the earth. Then turned He to the heaven, and fashioned it as seven heavens. And He is knower of all things. 29
