O men! serve your Lord Who created you and those before you so that you may guard (against evil). 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 ye are in doubt concerning that which We reveal unto Our slave (Muhammad), then produce a surah of the like thereof, and call your witness beside Allah if ye are truthful. 23 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 24 And bear thou the glad tidings unto those who believe and do righteous works that verily for them shall be Gardens whereunder rivers flow. So oft as they shall be provided with a fruit therefrom they will say: this is that wherewith we were provided afore; and they shall be vouchsafed that which is consimilar; and for them shall be therein spouses purified, and therein they shall be abiders. 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 who break Allah's covenant after ratifying it; who cut asunder what Allah has ordered to be joined, and who produce chaos on the Earth. These are the people who are indeed 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 It is He Who created for you all that is in the earth; then He inclined towards the heaven, therefore fashioning it as proper seven heavens; and He knows everything. 29
