O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 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 be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers. 24 And convey good news to those who believe and do good deeds, that they shall have gardens in which rivers flow; whenever they shall be given a portion of the fruit thereof, they shall say: This is what was given to us before; and they shall be given the like of it, and they shall have pure mates in them, and in them, they shall abide. 25 ۞ Well, Allah is not ashamed to cite the similitude of a gnat or of something even more insignificant than this. As for those who believe, they come to know from the same similitude that it is the Revelation from their Lord; but those who disbelieve, say, "What does Allah mean by such similitudes?" Allah leads astray many and guides many to the right way by the same thing. And He leads astray only those who disobey Allah; 26 Who break the covenant of Allah after the ratification thereof, and sunder that which Allah hath commanded should be joined, and act corruptly on the earth. These! they are the losers. 27 How can ye reject the faith in Allah?- seeing that ye were without life, and He gave you life; then will He cause you to die, and will again bring you to life; and again to Him will ye return. 28 He created for you all that is in the earth, then, He willed to the heaven, and leveled them seven heavens. He has knowledge of all things. 29
