Allah knows what every female bears, and by how much the wombs fall short (of their time or number) or exceed. Everything with Him is in (due) proportion. 8 [He is] Knower of the unseen and the witnessed, the Grand, the 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 For him are angels in succession, before him and behind him; they guard him with Allah's command. Verily Allah altereth not that which is with a people until they alter that which is with themselves. And when Allah intendeth evil unto a people there is no turning it back; nor is for them, beside Him, any patron. 11 He it is Who causes you to see lightning that inspires you with both fear and hope, and He it is Who whips up heavy clouds. 12 And Ar-Ra'd (thunder) glorifies and praises Him, and so do the angels because of His Awe, He sends the thunderbolts, and therewith He strikes whom He wills, yet they (disbelievers) dispute about Allah. And He is Mighty in strength and Severe in punishment. 13 To call on Him is true (supplication). For those they invoke other than Him do not answer them at all, except like a man who stretches his hands towards the water that it reach his mouth, but it will never reach it. Not more than error are the prayers of infidels. 14 And unto Allah falleth prostrate whosoever is in the heavens and the earth, willingly or unwillingly, as do their shadows in the morning and the evening hours. ۩ 15 Say: 'Who is the Lord of the heavens and of the earth?' Say: 'God.' Say: 'Then have you taken unto you others beside Him to be your protectors, even such as have no power to profit or hurt themselves?' Say: 'Are the blind and the seeing man equal, or are the shadows and the light equal? Or have they ascribed to God associates who created as He created, so that creation is all alike to them?' Say: 'God is the Creator of everything, and He is the One, the Omnipotent.' 16 He sends down water from the skies, which flows in channels according to their capacity, with the scum borne on the surface of the torrent, as rises the scum when metals are heated on the fire for making ornaments and household utensils. This is how God determines truth and falsehood. The scum disappears like the foam on the bank, and that which is useful to man remains on the earth. That is how God sets forth precepts of wisdom. 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
