O MANKIND! Worship your Sustainer, who has created you and those who lived before you, so that you might remain conscious of Him 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 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 - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers. 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 propound a similitude, be it of a gnat or of aught above it. Then as to those who believe, they know that it is the truth from their Lord. And to those who disbelieve, they say what intendeth God by similitude? He sendeth many astray thereby, and He guideth many thereby, and He sendeth not astray thereby any except the transgressors, 26 such as break the covenant of God after its solemn binding, and such as cut what God has commanded should be joined, and such as do corruption in the land -- they shall be the losers. 27 Then how can you disbelieve in God? He gave you life when you were dead. He will make you die again then bring you back to life: To Him then you will return. 28 It is He who created for you all of that which is on the earth. Then He directed Himself to the heaven, [His being above all creation], and made them seven heavens, and He is Knowing of all things. 29
