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 knows both what is hidden and what is manifest. He is the Supreme One, the Most High. 9 It is the same (to Him) whether any of you conceal his speech or declare it openly, whether he be hid by night or go forth freely by day. 10 For each (such person) there are (angels) in succession, before and behind him: They guard him by command of Allah. Allah does not change a people's lot unless they change what is in their hearts. But when (once) Allah willeth a people's punishment, there can be no turning it back, nor will they find, besides Him, any to protect. 11 It is He who shows you lightening, [causing] fear and aspiration, and generates the heavy clouds. 12 The thunder sings His praises, and the angels too, for awe of Him. He sends thunder-bolts and strikes whosoever He will with them: Even then it is God they contend about! But mighty is He in (His) power. 13 Unto Him [alone] is due all prayer aiming at the Ultimate Truth, since those [other beings or powers] whom men invoke instead of God cannot respond to them in any way - [so that he who invokes them is] but like one who stretches his open hands towards water, [hoping] that it will reach his mouth, the while it never reaches him. Hence, the prayer of those who deny the truth amounts to no more than losing oneself in grievous error. 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 Lord of the heavens and earth?" Say, "Allah." Say, "Have you then taken besides Him allies not possessing [even] for themselves any benefit or any harm?" Say, "Is the blind equivalent to the seeing? Or is darkness equivalent to light? Or have they attributed to Allah partners who created like His creation so that the creation [of each] seemed similar to them?" Say, "Allah is the Creator of all things, and He is the One, the Prevailing." 16 He sendeth down water from the heaven, so that the valleys flow according to their measure; then the torrent beareth the scum on top, and from that over which they kindle a fire seeking ornament or goods - ariseth a scum like thereto: Thus doth Allah propound the truth and falsity. Then as for the scum, it departeth as rubbish, and as for that which benefiteth the mankind, it lasteth on the earth: Thus doth Allah propound the similitudes. 17 of those who have responded to their Sustainer with a goodly response, and of those who did not respond to Him. [As for the latter,] if they possessed all that is on earth, and twice as much, they would surely offer it as ransom [on the Day of Judgment]: a most evil reckoning awaits them, and their goal is hell: and how evil a resting-place! 18
