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 is the Knower of the Invisible and the Visible, the Great, the High Exalted. 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 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 It is He who shows you the lightning, for fear and hope, and Who produces laden clouds. 12 the thunder proclaims His praise, and the angels, in awe of Him. He looses the thunderbolts, and smites with them whomsoever He will; yet they dispute about God, who is mighty in power. 13 For Him (Alone) is the Word of Truth (i.e. none has the right to be worshipped but He). And those whom they (polytheists and disbelievers) invoke, answer them no more than one who stretches forth his hand (at the edge of a deep well) for water to reach his mouth, but it reaches him not, and the invocation of the disbelievers is nothing but an error (i.e. of no use). 14 All that is in the heavens and the earth prostrates itself, whether willingly or by force, before Allah; and so do their shadows in the morning and in the evening. ۩ 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 sends down out of heaven water, and the wadis flow each in its measure, and the torrent carries a swelling scum; and out of that over which they kindle fire, being desirous of ornament or ware, out of that rises a scum the like of it. So God strikes both the true and the false. As for the scum, it vanishes as jetsam, and what profits men abides in the earth. Even so God strikes His 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
