God knows what any female bears [in her womb,] and by how much the wombs may fall short [in gestation,] and by how much they may increase [the average period]: for with Him everything is [created] in accordance with its scope and purpose. 8 He is the Knower of the Invisible and the Visible, the Great, the High Exalted. 9 Alike of you is he who conceals his -- saying, and he who proclaims it, he who hides himself in the night, and he who sallies by day; 10 [thinking that] he has hosts of helpers - both such as can be perceived by him and such as are hidden from him - that could preserve him from whatever God may have willed. Verily, God does not change men's condition unless they change their inner selves; and when God wills people to suffer evil [in consequence of their own evil deeds,] there is none who could avert it: for they have none who could protect them from Him. 11 It is He who shows you the lightning, as a fear (for travellers) and as a hope (for those who wait for rain). And it is He Who brings up (or originates) the clouds, heavy (with water). 12 The thunder hymneth His praise and (so do) the angels for awe of Him. He launcheth the thunderbolts and smiteth with them whom He will while they dispute (in doubt) concerning Allah, and He is mighty in wrath. 13 Unto Him is the real prayer. Those unto whom they pray beside Allah respond to them not at all, save as (is the response to) one who stretcheth forth his hands toward water (asking) that it may come unto his mouth, and it will never reach it. The prayer of disbelievers goeth (far) astray. 14 And to Allah prostrates whoever is within the heavens and the earth, willingly or by compulsion, and their shadows [as well] in the mornings and the afternoons. ۩ 15 Say: "Who is the Sustainer of the heavens and the earth?" Say: "[It is] God." Say: "[Why,] then, do you take for your protectors, instead of Him, such as have it not within their power to bring benefit to, or avert harm from, themselves?" Say: "Can the blind and the seeing be deemed equal? - or can the depths of darkness and the light be deemed equal?" Or do they [really] believe that there are, side by side with God, other divine powers that have created the like of what He creates, so that this act of creation appears to them to be similar [to His]? Say: "God is the Creator of all things; and He is the One who holds absolute sway over all that exists." 16 He sends down water (rain) from the sky, and the valleys flow according to their measure, but the flood bears away the foam that mounts up to the surface, and (also) from that (ore) which they heat in the fire in order to make ornaments or utensils, rises a foam like unto it, thus does Allah (by parables) show forth truth and falsehood. Then, as for the foam it passes away as scum upon the banks, while that which is for the good of mankind remains in the earth. Thus Allah sets forth parables (for the truth and falsehood, i.e. Belief and disbelief). 17 Those who answer the call of their Lord will receive good rewards. Whatever those who have not answered the call of their Lord offer to redeem themselves, even if they offer double the wealth of the whole earth, will not be accepted. They will face a terrible reckoning and their dwelling will be hell, a terrible place to rest! 18
