God alone has knowledge of the hidden reality of the heavens and the earth; and the coming of the Hour [of Judgement] is like the twinkling of an eye, or even quicker. Surely God has full power over everything. 77 And Allah has extracted you from the wombs of your mothers not knowing a thing, and He made for you hearing and vision and intellect that perhaps you would 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 houses places of rest for you and made tents for you out of cattle hides, which are light for you to carry, both when you are travelling and when you are staying in one place. He provides for you from the wool and fur and hair of cattle, household goods and articles for use for a time. 80 And among the many objects of His creation, God has appointed for you [various] means of protection: thus, He has given you in the mountains places of shelter, and has endowed you with [the ability to make] garments to protect you from heat [and cold,] as well as such garments as might protect you from your [mutual] violence. In this way does He bestow the full measure of His blessings on you, so that you might surrender yourselves unto Him. 81 Then, if they turn away, your duty (O Muhammad SAW) is only to convey (the Message) in a clear way. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
