Al-Anbya 31: And We have raised mountains from the earth so that they will not be shaken. And We have made widened roads on it, so that they will be guided.

So that it would not shake them, We set up mountains on the earth. And We opened wide roads there. So that they may reach their destinations. yes now on the earth, the mountains, so that the world would not shake, were created. How would the world shake? If there were no mountains and, beneath these mountains, water reservoirs, if the Earth had not turned on its own axis at 1666-odd, if, due to centrifugal force, the world's being flung, its flinging, had not existed, with certain imbalances made on the earth, the world would turn wobbling. And sometimes it would pile up to one side, and sometimes to one side — to the other side — turning and drifting unbalanced.

Allah Almighty, to ensure that the earth turns in balance — since He knows what will be done on the world: atoms being dropped, the earth's spheres bursting, volcanoes erupting, earthquakes occurring, and people's atomic tests or bomb tests on the earth — in such events, in places where the earth will take some force and its balance will be disturbed — since He knows, sir, what will happen there, so that the world will not shake beyond those balances, He turns the world with centrifugal force, and wherever on the world an abnormal situation arises, it does not affect the world. Yes. Now, the helicopter — think of it: it has 3 propellers on top, or 2 propellers.

If you took hold of these propellers and lifted the helicopter, the propellers would break. They wouldn't lift the helicopter. These propellers start to turn. When they start to turn, if they turn abnormally, then the goal is not reached. If they turn too little, again the goal is not reached. Through testing, they reduced the engine's 2400 revolutions at a ratio of one in 11. With the engine at 2400 revolutions, the propeller makes 240 revolutions per minute. In this case, at the tip of each of the propellers, at the blade tips, a pulling force of 20 tons arises. With two propellers, a pulling force of 40 tons arises.

It whirls a helicopter of two, two and a half, three tons around with ease.

Yes. Allah Almighty, too, placed the mountains on the earth in this way, and put water reservoirs beneath them; by turning the world on its own axis in 24 hours at a speed of 40 thousand kilometres, due to this centrifugal force, with any imbalance made anywhere on the world, Allah Almighty keeps the world on its course in such a way that it does not affect the world.

So — how was it, I don't know. Yes.

Allah Almighty goes on describing the power of creation, one of His divine attributes. Created beings cannot accomplish these things He describes, even with knowledge. He declares that He set firm mountains on the earth and thereby prevented the earth from shaking. Today's science has proven that beneath the mountains it is full of water, of water. And mountains are the weakest outer points of the world. We think mountains are the world's highest peaks. Yet since the world is round, mountains are the world's weakest outermost parts. Its pointed parts. Beneath the mountains, in valleys, in plains we live. We are in the lower parts of the world.

Whereas mountains are its outer parts. That is why water flows from the mountain tops, from the weakest point, downward. If mountains were high up as we see them, on the world's elevation, water surely would not go uphill. It wouldn't flow. So He prevents the earth from shaking, He declares. And today's science has proven that beneath the mountains it is full of water. And mountains are the world's weakest outermost points. That is why water flows down from the mountain tops. The water reservoirs beneath these mountains, with the world's turning on its own axis, produce a flinging due to centrifugal force.

So, so that no unbalanced flinging occurs, the waters located beneath the mountains, while being flung with the world's turning, due to centrifugal force, prevent the world's unbalanced rotation. They ensure it turns within a certain order, system and regularity. Like what? What is centrifugal force? Centrifugal force? It is, while being flung, pulling the world with a force toward one side. The world. As it turns on its own axis, with a pull from four sides, with this pulling, if a pull arises from every side, such unbalanced movements occurring inside the world cannot overcome the strength of this pull, so the world turns easily on its own axis.

"Between the mountains We opened wide roads" — when He says this: Allah Almighty created the mountains of many kinds, large and small. Through their travels, people know where these mountains are and to which region these mountains belong, and set their routes accordingly. Also, a Sufi matter here I cannot pass over without explaining. Mountains have not been placed at random. Mountains both maintain the world's balance and, as the world turns, just like the keys of a piano, the mountains, as it turns on its axis, give out a sound. A sound. This sound is the sound of Mevlana's ney, you know — that sound.

That blessed man heard that sound and attuned the ney to that sound. How do you know? By Allah, I experienced it too. I swear it. The same sound. If Allah opens a person's unveiling, he hears it.

So even the mountains are not random.

In today's technology, although planes, with what we call radio range, using the frequencies of certain places, determine their heading with the radio compass device, in clear weather, while in flight, with the maps in hand, they know by the locations of mountains and the particular marks of plains and rivers where they are. So Allah, so that people on the earth can easily find their way, has furnished this world with knowledge. yes

These (?) devices exist. Radio sets. In addition, there is a device we call radio range. (?) there is a signal. A signal that this radio range sends out. For example, let's say, as an example, Ankara: two long, one short. it beats dit dit dit, continuously dit dit dit, for example I'm saying Istanbul, as an example; it beats dit dit dit dit dit dit dit dit; this when the plane takes off — where will it go? To Istanbul — when it sets the radio range's frequency, the needle constantly points there, toward Istanbul. however overcast the weather may be.

How does the pilot know he has arrived over Istanbul? How does he know he has arrived over that airfield?

The needle swings all the way back. If it passes over Istanbul, that (?), the needle swings all the way back. He knows he is over Istanbul. The radar catches him anyway. With the radar, sir, connecting as required to the operator in the tower, it brings it down too.

Is our lesson a technology lesson?

Let's read (?). Yes.
