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 And Allah has brought you forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts that you may give thanks. 78 Do you not see the birds held high between the heavens and the earth? Nothing holds them (aloft) but God. There are verily signs in this for those who believe. 79 And Allah has given you houses for staying, and made some houses from the hides of animals, which are easy for you on your day of travel and on the day of stopover – and from their wool, and fur, and hair, some household items and utilities for a while. 80 And Allah has provided shade for you out of some of the things He has created; and He has provided you with shelters in the mountains, and has given you coats that protect you from heat as well as coats that protect you in battle. Thus does He complete His favour upon you that you may submit to Him. 81 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
