O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (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 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 you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 24 And bear thou the glad tidings unto those who believe and do righteous works that verily for them shall be Gardens whereunder rivers flow. So oft as they shall be provided with a fruit therefrom they will say: this is that wherewith we were provided afore; and they shall be vouchsafed that which is consimilar; and for them shall be therein spouses purified, and therein they shall be abiders. 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 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 made for you all that lies within the earth, then turning to the firmament He proportioned several skies: He has knowledge of everything. 29
