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 you are in doubt as to that which We have revealed to Our servant, then produce a chapter like it and call on your witnesses besides Allah if you are truthful. 23 But if you fail, as you are sure to fail, then guard yourselves against the Fire whose fuel is people and stones, prepared for the unbelievers. 24 And give glad tidings to those who believe and do good deeds; that for them are Gardens beneath which rivers flow; when they are provided with a fruit of the Gardens, they will say, “This is the same food as what was given to us before” whereas it is in resemblance; and in the Gardens are pure spouses for them; and they shall abide in it forever. 25 ۞ Indeed Allah does not, for the sake of explanation, shy to illustrate an example of anything, whether it is of a gnat or something further (inferior) than it; so the believers know it is the Truth from their Lord; as for the disbelievers, they say, “What does Allah intend by such an example?” He misleads many thereby, and He guides many thereby; and with it He misleads only those who are rebellious. 26 those who break God's covenant after they have pledged to keep it, and sever whatever God has ordered to be joined, and spread corruption in the land -- it is they who are the losers. 27 How dare you deny the existence of God Who gave you life when you initially had no life. He will cause you to die and bring you to life again. Then you will return to His Presence. 28 It is He Who hath created for you all things that are on earth; Moreover His design comprehended the heavens, for He gave order and perfection to the seven firmaments; and of all things He hath perfect knowledge. 29
