Allah knows all what is inside the womb of every female, and every increase and decrease of the wombs; and all things are with Him by a set measure. 8 He knows both what is hidden and what is manifest. He is the Supreme One, the Most High. 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 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, inspiring fear and hope, and gathers up the 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 The only true appeal is to God alone; those they appeal to instead of Him will never respond to them in any way. They are like a man who stretches forth his hands toward the water, so that it may reach his mouth, but it never does. The calls of those who deny the truth are all in vain. 14 And whoever is in the heavens and the earth makes obeisance to Allah only, willingly and unwillingly, and their shadows too at morn and eve. ۩ 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 He sends down from the sky, rain, and valleys flow according to their capacity, and the torrent carries a rising foam. And from that [ore] which they heat in the fire, desiring adornments and utensils, is a foam like it. Thus Allah presents [the example of] truth and falsehood. As for the foam, it vanishes, [being] cast off; but as for that which benefits the people, it remains on the earth. Thus does Allah present examples. 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
