Allah knows what every female bears; and what the wombs fall short of (in gestation), and what they may add. With Him everything is in a fixed measure. 8 The knower of the unseen and the seen, the Great, the Most High. 9 He who keeps his secret among you is the same to Him as he who speaks out publicly, and he who hides himself in the night and walks freely in the day. 10 For his sake there are angels following one another, before him and behind him, who guard him by Allah's commandment; surely Allah does not change the condition of a people until they change their own condition; and when Allah intends evil to a people, there is no averting it, and besides Him they have no protector. 11 It is He who makes the lightning flash for fear and hope, and raises massive clouds. 12 The thunder exalts His praise, and so are the angels are in awe of Him. He looses the thunderbolts and smites whosoever He will. Yet they dispute about Allah who is Mighty in power. 13 To Him is the call of truth; and those upon whom they call, apart from Him, answer them nothing, but it is as a man who stretches out his hands to water that it may reach his mouth, and it reaches it not. The prayer of the unbelievers goes only astray. 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 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 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 obey their Lord is excellence. For those who fail to obey, the reckoning will be hard, even if they possess and give as ransom all that there is on the earth, and as much more; and Hell will be their abode: How wretched is its wide expanse! 18
