O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 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 (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Quran) to Our slave (Muhammad Peace be upon him), then produce a Surah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allah, if you are truthful. 23 But if you do it not, and you can never do it, then fear the Fire (Hell) whose fuel is men and stones, prepared for the disbelievers. 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 ۞ 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 who break their established covenant with Him and the relations He has commanded to be kept and who spread evil in the land. These are the ones who lose a great deal. 27 How can you disbelieve Allah? Did He not give you life when you were dead, and He will cause you to die and then restore you to life. Then you will return to Him. 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
