O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who has made the earth a bed for you and the sky a dome, and has sent down water from the sky to bring forth fruits for your provision. Do not knowingly set up rivals to Allah. 22 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) 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 And give good news (O Muhammad), to those who believe in this Book and do good deeds (in accordance with its teachings). For them there will be gardens underneath which canals flow. Their fruits will so resemble the fruits on the Earth that every time they will be provided with fruits, they will say, "Such fruits were provided to us before on the Earth. " And there will be pure spouses for them and therein they will live for ever. 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 such as break the covenant of God after its solemn binding, and such as cut what God has commanded should be joined, and such as do corruption in the land -- they shall be the losers. 27 How will ye disbelieve in Allah whereas ye were lifeless and he quickened you; thereafter He will cause you to die, thereafter He will give you life, thereafter unto Him ye shall be returned! 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
