And unto Allah belongeth the Unseen of the heavens and the earth, and the matter of the Hour (of Doom) is but as a twinkling of the eye, or it is nearer still. Lo! Allah is Able to do all things. 77 God brought you forth from the wombs of your mothers while you knew nothing, and gave you hearing and sight and hearts, so that you might be grateful. 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 God has given you homes to live in, and tents (made) from the hides of cattle convenient for days of travelling and halting; and from their wool and fur and hair you make domestic articles and goods that last a certain time. 80 And Allah has made for you, from that which He has created, shadows and has made for you from the mountains, shelters and has made for you garments which protect you from the heat and garments which protect you from your [enemy in] battle. Thus does He complete His favor upon you that you might submit [to Him]. 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They recognize the favor of Allah; then they deny it. And most of them are disbelievers. 83
