"He (Allah) is the Creator of the heavens and the earth..." (Surat ash-Shura: 11)
Allah is the One Who created earth, the Sun, stars and Moon. So how did all the living things on earth come into being? Imagine a huge planet with its surface completely empty. There are no humans or animals, no plants or insects.
Earth has been decorated in a lot of detail for living things to survive. Allah is the One Who has given earth all these details. Otherwise none of us would have been able to live, neither you, nor your parents, or indeed any of your friends would have been here.
Let's consider how Allah created the earth so that living things can survive:
1. Think about… how orderly everything in the universe is. The sun has been put in the exact position from which it could warm us and give us light at the same time. If there were no sun, there would not have been one living thing on earth. Neither us, nor the animals nor any other creatures would have been able to live.
2. Allah has also distanced the sun from earth to just the right extent. If earth was a little bit closer to the sun, the heat would have scorched it and we would not have been able to live. If earth was a little more distant from the sun, then glaciers would have covered it and again, few living things would have been able to survive. This is one of the reasons why there is no life on other planets, because they are either too close to the sun or too distant from it.
3. As you know, living things need to breathe in order to live. We need oxygen in the air so that we can breathe. Exactly the right amount of oxygen exists in the air so that human beings can breathe. If there were a little bit more or a little bit less, neither we, nor the animals, nor the plants would have survived, because, as we have already said, we need to breathe in order to live. For this we need oxygen.
4. One of the most important things that make it possible for us to survive is water. No organism can live without water. For this reason, Allah has created some parts of earth as water. Three quarters of earth's surface is covered with water. However, there is no water on any of the other planets nor is there any water on the moon that you see at night. The essentials for living things are only available on earth.
Many events on earth make it possible for us to live. If even only one of these events doesn't take place, no living thing would be left on earth. So, is it possible that these thousands of events have come together spontaneously and formed such a place as earth? Of course not. Not even one of these events could happen by chance. Allah has created earth for human beings. And, because of this, earth is the most suitable place for us.

The miracle of respiration
The miracle of respiration
People do many different things in their daily lives.
But whatever they do, they still have to keep breathing.
Yet they never need to make a conscious effort in order to breathe.
Neither do they use their free will in order to breathe. They breathe right from the moment of their birth, even in their sleep.
The brain is the command center for the whole process of respiration.
A group of nerves in the brain stem and the medulla region of the brain direct the respiratory system.
The nerves in the medulla send commands to the muscles surrounding the ribcage to contract for two seconds. As the muscles contract the lungs fill with air.
Then, the nerve signals from the medulla are cut for three seconds. The muscles then relax. The air in the lungs is then expelled as the muscles assume their earlier form.
Directed by the medulla, breathing takes around five seconds: two seconds for inhaling and three for exhaling. Under normal conditions a healthy person breathes some 12 times a minute.
Yet that figure goes up under certain circumstances.
If you exercise, you’ll see that your breathing rate rises considerably. Yet it is not you who has decided to breathe quickly at this moment, your chest muscles are forcing you to, and you feel discomfort if you try to breathe slowly. Since you are working out, your tissues has a greater need for oxygen and your brain obliges you to breathe faster. In the same way that your breathing under normal conditions is out of your control, so is the way when you are breathing quickly.
Control of breathing is thus independent of an individual’s will.
When the muscles work more than under normal conditions they consume more oxygen. As the level of oxygen in the blood falls, the level of carbon dioxide rises.
Muscle cells under pressure give off lactic acid.
The oxygen, carbon dioxide and lactic acid receptors in various parts of the body become aware of this change and send warnings to the respiratory centre in the brain.
When the warning reaches the medulla, the respiratory neurons send commands to the chest muscles and ensure that they work faster.
On the other hand, other precautions are also taken in the body. The heart starts beating faster, for instance. The skin pores are opened in order to balance the rise in body temperature and attempts to cool the body down.
When pressure on the muscles is lifted, all the systems gradually return to their normal conditions.
The flawless, interconnected systems work and serve beyond the individual’s control, will and knowledge.
Man’s duty is thus to give thanks to Allah, Who created him with such perfection, and to appreciate the artistry in His creation.
In one verse of the Qur’an, Allah reveals:
He is Allah – the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and earth glorifies Him. He is the Almighty, the Wise.............
