When you look at these lines, an electric current traveling at 500 km per hour (310.7 mph) begins moving from your eyes to your brain by any of its 600,000 nerves. When the current is transmitted, you begin reading the lines before you.
The eye is linked to the brain by 600,000 nerves, which simultaneously receive and arrange 1.5 million messages at the same time and send them to the brain at 500 km an hour (310,7 mph). When you look at a single point, you actually see hundreds of different details that the eye distinguishes from all of the massages reaching it and then analyzes and forwards to the brain. While this book you are holding is quite close to you, the scene you see in the background is, at the same time, comparatively far away. And yet you see both of them with the same clarity, for not a single point in your line of sight is overlooked or unclear. No matter how detailed the view you are looking at is, even the image of a small ant that happens to be in your line of sight reaches your brain.
No camera or television could provide such a high degree of clearness, and so all man-made technology is inferior to the human eye. If people are deprived of this blessing, they will be unable to see anything until this system is restored. And that can only happen by Allah ’s choosing.
This special blessing, created for human beings while they are still embryos, is a gift from Allah, Who is always needed and from Whom aid may be hoped for at all times:
Say: “It is He Who brought you into being and gave you hearing, sight, and hearts. What little thanks you show!’ (Surat al-Mulk, 23)
