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 It makes no difference whether you converse in secret or aloud, whether you hide under the cloak of night or walk about freely in the light of day. 10 His angels keep watch over him in succession (night and day), in front and behind, by God's command. Verily God does not change the state of a people till they change themselves. When God intends misfortune for a people no one can avert it, and no saviour will they have apart from Him. 11 It is He who shows you the lightning, for fear and hope, and produces the heavy clouds; 12 and the thunder extols His limitless glory and praises Him, and [so do] the angels, in awe of Him; and He [it is who] lets loose the thunderbolts and strikes with them whom He wills. And yet, they stubbornly argue about God, notwithstanding [all evidence] that He alone has the power to contrive whatever His unfathomable wisdom wills! 13 For Him (Alone) is the Word of Truth (i.e. none has the right to be worshipped but He). And those whom they (polytheists and disbelievers) invoke, answer them no more than one who stretches forth his hand (at the edge of a deep well) for water to reach his mouth, but it reaches him not, and the invocation of the disbelievers is nothing but an error (i.e. of no use). 14 All in the heavens and the earth prostrate themselves before God, either of their own free will or by force, just as do their shadows in the mornings and evenings. ۩ 15 Say: Who is the Lord of the heavens and the earth?-- Say: Allah. Say: Do you take then besides Him guardians who do not control any profit or harm for themselves? Say: Are the blind and the seeing alike? Or can the darkness and the light be equal? Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme. 16 [Whenever] He sends down water from the sky, and [once dry] river-beds are running high according to their measure, the stream carries scum on its surface; and likewise, from that [metal] which they smelt in the fire in order to make ornaments or utensils, [there rises] scum. In this way does God set forth the parable of truth and falsehood: for, as far as the scum is concerned, it passes away as [does all] dross; but that which is of benefit to man abides on earth. In this way does God set forth the parables 17 For those who respond to their Lord is good; and (as for) those who do not respond to Him, had they all that is in the earth and the like thereof with it they would certainly offer it for a ransom. (As for) those, an evil reckoning shall be theirs and their abode is hell, and evil is the resting-place. 18
