O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who hath appointed the earth a resting-place for you, and the sky a canopy; and causeth water to pour down from the sky, thereby producing fruits as food for you. And do not set up rivals to Allah when ye know (better). 22 If you are in doubt of what We have sent down to Our worshiper (Prophet Muhammad), produce a chapter comparable to it. Call upon your helpers, other than Allah, to assist you, if you are true. 23 But if ye cannot- and of a surety ye cannot- then fear the Fire whose fuel is men and stones,- which is prepared for those who reject Faith. 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 the covenant of Allah after its confirmation and cut asunder what Allah has ordered to be joined, and make mischief in the land; these it is that are the losers. 27 How is it that you adopt the attitude of disbelief towards Allah when the fact is that you were lifeless and He gave you life, and He will take away life from you and will again restore you to life: then you shall ultimately return to Him. 28 He it is Who created for you all that is on earth. Then He Istawa (rose over) towards the heaven and made them seven heavens and He is the All-Knower of everything. 29
