O you men, serve your Lord Who created you, and those that were before you; haply so you will be godfearing; 21 Who has made the earth a resting place for you, and the sky as a canopy, and sent down water (rain) from the sky and brought forth therewith fruits as a provision for you. Then do not set up rivals unto Allah (in worship) while you know (that He Alone has the right to be worshipped). 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 And if you cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones which awaits all who deny the truth! 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 ۞ God is not ashamed to strike a similitude even of a gnat, or aught above it. As for the believers, they know it is the truth from their Lord; but as for unbelievers, they say, 'What did God desire by this for a similitude?' Thereby He leads many astray, and thereby He guides many; and thereby He leads none astray save the ungodly 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 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 It is He who created for you all that is in the earth, then He lifted Himself to heaven and levelled them seven heavens; and He has knowledge of everything. 29
