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 Knower of the hidden and the manifest! the Great! the Exalted. 9 Alike (to Him) among you is he who conceals (his) words and he who speaks them openly, and he who hides himself by night and (who) goes forth by day. 10 Each has guardian angels before him and behind him, who watch him at God's command. God does not change the condition of a people's lot, unless they change what is in their hearts. But when God decrees punishment for a people, none can ward it off. Besides Him, they have no protector. 11 HE IT IS who displays before you the lightning, to give rise to [both] fear and hope, and calls heavy clouds into being; 12 And the thunder proclaims His purity with praise, and the angels out of fear of Him; and He sends the bolt of lightning – it therefore strikes upon whom He wills, whilst they are disputing concerning Allah; and severe is His seizure. 13 To Him [alone] is the supplication of truth. And those they call upon besides Him do not respond to them with a thing, except as one who stretches his hands toward water [from afar, calling it] to reach his mouth, but it will not reach it [thus]. And the supplication of the disbelievers is not but in error [i.e. futility]. 14 All that is in the heavens and the earth prostrates itself, whether willingly or by force, before Allah; and so do their shadows in the morning and in the evening. ۩ 15 Say, "Who is Lord of the heavens and the earth?" Say, "God." Say, "Why do you take protectors other than Him, who can neither benefit nor harm even themselves?" Say, "Are the blind and the seeing equal? Is darkness equal to the light? Or have they assigned partners to God who create as He creates, so that both creations appear to them alike?" Say, "God is the Creator of all things. He is the One, the Almighty." 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 There will be the best of rewards for those who respond to their Lord: while those who do not respond to Him -- if they possessed all that is on earth and twice as much, they would surely offer it as ransom [on the Day of Judgement]; -- will have the worst reckoning and their goal is Hell: and how evil a resting-place! 18
