And God's [alone] is the knowledge of the hidden reality of the heavens and the earth. And so, the advent of the Last Hour will but manifest itself [in a single moment,] like the twinkling of an eye, or closer still: for, behold, God has the power to will anything. 77 God produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may be grateful. 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 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 80 God has provided shade for you out of what He has created and places of retreat out of mountains. He has given you garments to protect you from the heat and cover your private parts. This is how He perfects His bounties to you so that perhaps you would submit to His will. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
