O Mankind worship your Lord who hath created you and those before you, haply ye may become God-fearing 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 Should you have any doubt about what We have revealed to Our servant, present one chapter comparable to it and call all your supporters, besides God, if your claim is true. 23 But if ye do it not, and by no means ye shall, then dread the Fire, the fuel whereof is men and stones, gotten ready for the infidels. 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 ۞ 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 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 He it is who has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
