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 is the knower of the known and the unknown, the mighty and most high. 9 It is the same (to Him) whether any of you conceal his speech or declare it openly; whether he lie hid by night or walk forth freely 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 lightening, [causing] fear and aspiration, and generates the heavy clouds. 12 And the thunder halloweth His praise, and so do the angels in awe of Him; and He sendeth the thunderbolts and smiteth therewith whomsoever He will. And they dispute concerning Allah, and He is strong in prowess. 13 To Him alone should all prayer be addressed, for those to whom they do address their prayers beside Him are altogether powerless to respond to them. The example of praying to any other than Allah is that of a man who stretches out his hands to water, asking it to reach his mouth, although water has no power to reach his mouth. The prayers of the unbelievers are a sheer waste. 14 Whatever beings there are in the heavens and the earth do prostrate themselves to Allah (Acknowledging subjection),- with good-will or in spite of themselves: so do their shadows in the morning 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 He sendeth down water from the sky, so that valleys flow according to their measure, and the flood beareth (on its surface) swelling foam - from that which they smelt in the fire in order to make ornaments and tools riseth a foam like unto it - thus Allah coineth (the similitude of) the true and the false. Then, as for the foam, it passeth away as scum upon the banks, while, as for that which is of use to mankind, it remaineth in the earth. Thus Allah coineth the similitudes. 17 For those who respond to their Lord, are (all) good things. But those who respond not to Him,- Even if they had all that is in the heavens and on earth, and as much more, (in vain) would they offer it for ransom. For them will the reckoning be terrible: their abode will be Hell,- what a bed of misery! 18
