To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 And Allah has brought you out from the wombs of your mothers while you know nothing. And He gave you hearing, sight, and hearts that you might give thanks (to Allah). 78 Have they not seen the birds, subservient in the open skies? No one holds them up except Allah; indeed in this are signs for the people who believe. 79 And God has given you [the ability to build] your houses as places of rest, and has endowed you with [the skill to make] dwellings out of the skins of animals - easy for you to handle when you travel and when you camp - and [to make] furnishings and goods for temporary use of their [rough] wool and their soft furry wool and their hair. 80 God has granted you shade out of what He has created, places of shelter in the mountains, garments with which to protect yourselves from the heat and coats of mail to shield you in battle. Thus He completes His favour to you, so that you may submit wholly to Him. 81 But if they turn away, thy duty is only to preach the clear Message. 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
