O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth). 22 And if you doubt any part of what We have bestowed from on high, step by step, upon Our servant [Muhammad,] then produce a surah of similar merit, and call upon any other than God to bear witness for you if what you say is true! 23 But if you do (it) not and never shall you do (it), then be on your guard against the fire of which men and stones are the fuel; it is prepared for the unbelievers. 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 loath to advance the similitude of a gnat or a being more contemptible; and those who believe know whatever is from the Lord is true. But those who disbelieve say: "What does God mean by this parable?" He causes some to err this way, and some He guides; yet He turns away none but those who transgress, 26 who break their bond with God after it has been established [in their nature,] and cut asunder what God has bidden to be joined, and spread corruption on earth: these it is that shall be 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 in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
