For example, if you are walking down the street and a man riding a car approaches you from your back, and honks the horn.. Your brain possesses a very sophisticated systemthat calculates the time the sound takes to reach each ear and the lag between them, which is about 1/1620 second. This system then determines that the sound comes from the right for instance, and thus lets you know that you should move to the left. Does anyone of you know that he owns this system that tells him the direction of sounds?
I was driving back to Damascus from Homs, when suddenly a flock of sheep passed the street.I honked the horn and the sheep started moving to the left to give my car room to pass. This means that this sophisticated system exists in the rest of creatures (not only man) to protect them from danger.
This is the meaning of Allah's Name "Al Musallem" (safety provider), for He protects us from every danger.
Pondering over the creation of the heavens and the earth is considered the shortest path to Allah and the widest doorway to draw closer to Allah.
Man is able to see due to the one and a third square millimeter retina that is placed in the fundus of the eye.
Before I carry on, you must know that the most advanced, complicated, digital, expensive camera whose price is not less than 5 million and that is used in TV shows has only 10.000 light receptors per 1 square millimeter, whereas the human eye has 100 million light receptors per 1 square millimeter.
This is why the accuracy of the human eye is amazing to such an extent that it can differentiate between about 8 million colors and 800 shades of each color.
Allah says:
﴾ Have We not made for him a pair of eyes? And a tongue and a pair of lips? And shown him the two ways (good and evil)? ﴿
When you use the camera to take a picture, its size is very small but when you look at a mountain using your eyes, you see it in its real size. This phenomenon is still a mystery.
Thus pondering is the closest way to Allah and the widest doorway to draw near Him.
Do you believe that the human liver performs more than 5,000 functions in the human body and that without a liver man can survive for only three hours, whereas man can live with a bad heart for 20 years and can cope with it?
Given the liver performs 5000 functions, every cell of the liver is capable alone of performing all those functions, namely, if a surgeon removes four fifth of the liver, the liver will reconstruct itself in 16 weeks.
What a sophisticated creation?
When man speaks,every letter he pronounces, requires the use of 17 muscles , thus if man speaks a word of five letters, he needs 17 times 5, 35 muscles to say it, and if the sentence contains five words, or man speaks for an hour, imagine how many muscles he would use.
﴾ The Most Beneficent (Allah)! Has taught (you mankind) the Qur'an (by His Mercy). He created man. He taught him eloquent speech. ﴿
Living without guidance to follow, is meaningless for man's existence:
One might ask: how is it possible that we learn the Quran before we are created?
﴾ The Most Beneficent (Allah)! Has taught (you mankind) the Qur'an (by His Mercy). He created man.
﴿
Interpreters said: "The order here is not chronicle but rather it is a rank correlation", namely, man's existence is meaningless without a method to follow.
Buying a very expensive, useful, and profitable machine, you need its manual to operate it, so if the company doesn't send the manual, the machine will be useless,and we might damage it by the misuse, and if we don't use it, we will throw away the money we paid for it. Thusthe manual is as important as the machine. Much in the same line, Allah's instructions are very important to man; the proof is in the following Ayah:
﴾ The Most Beneficent (Allah)! Has taught (you mankind) the Qur'an (by His Mercy). He created man. He taught him eloquent speech. ﴿
Ustaz Jamal, when man is asleep, the saliva gathers in his mouth, so an alert is sent to the brain: "too much saliva". The brain is awake. It sends orders to the epiglottis, to open the way to the esophagus and block the way to the lungs. All this happens while man is asleep and has no idea what is going on. Who created this delicate system?
When you are at the dentist and fixing your teeth might take long time, he uses a dental saliva ejector tube to remove the excessive saliva, while normally as Allah created us, your brain orders the epiglottis to open the way to the esophagus and block the way to the lungs while you are sleeping so that you may swallow the excessive saliva.
When you are asleep, the bones press on the muscles, and both the muscles and the bones press on the nerves and arteries. Thismakes the arteries become narrow, and as a result the blood flow is decreased in that area which causes numbness, but in such cases, the nerves ends which sense this pressure, send a signal to the brain which in turn orders the body to change your position and accordingly you turn your body to the other side
Allah says:
﴾ And We turned them on their right and on their left sides ﴿
Without repositioning during sleep, our muscles and skin would have rotted.
This is the reason why the person in a coma should be repositioned every now and then so that he won’t get skin sores and in order to prevent his body from rotting. Nowadays there are some very expensive beds which reposition the coma patients automatically
Man repositions his body nearly 40 times every night. Allah says:
﴾ And We turned them on their right and on their left sides ﴿
Had Allah said "on their right and on their right", one would have fallen off the bed.
﴾ And We turned them on their right and on their left sides ﴿
Ustaz Jamal! talking about this topic is very interesting and it draws us closer to Allah Almighty.
Ustaz Jamal:
Dr. Rateb, indeed talking about this topic brings us closer to Allah whether in our acts or worship or in obeying Him.
Allah is Great and by reflecting on His Greatness in His creation and His Miracles, we seek His pleasure (as you always say), His Mercy and His Bestowal.
We are still talking about man and his creation in this weekly meeting "Quran is Guidance for Mankind" and we will talk about man's skin which is miraculous in man's creation, so please go ahead.
Dr. Rateb:
Allah is Beautiful and loves beauty. If you look at a person without skin, his bones and muscles' appearance is scary. Even the symbol of horror is a skull and two crossed bones. Thus, man as a skeleton and muscles is scary, but the skin gives beauty to man's body, thus it has a esthetic purpose.
In addition, the skin has amazing features and speaking about them is very interesting.
Skin takes the first shocks, and within the skin there are sensory nerves that are spread wisely. You have to wash your hands three times a day at least, and your hand's skin can bear cold and hot water unlike the skin on your back . Also these nerves make man feel cold in cold weather in order to put on heavy clothes and protect the body from being harmed.
Thus, every part of the body has different kind of sensory nerves for the sake of man's safety and the spread of these nerves all over the skin is very important. Had these sensory nerves not existed, what would have happened?
The difference between the believer and the non-believer in quality is substantial:
It is said that we have a path of pain, and this path starts from the skin where the sensory nerves converge to form bigger nerves until they reach the spinal cord that is connected to the brain. There is what is called "pain doorways".
I know a man, who I assume is pious (and Allah is the judge over him), was inflicted with colon cancer. . Whenever a visitor came, he would say: "Be my witness that I am pleased with Allah, O Allah praise be to You" after one week, his room was visited by all the physicians and employees in the hospital, for this room brought peace to anyone who visited it.
A week later he died. Another person was admitted in this hospital with the same cancer and suffered the same pain as the first patient, only this patient was swearing and cursing and using harsh words.
Scientists discovered that through the path of pain, there are doorways, and if they were closed, the pain will be decreased to one tenth of its severity, whereas if they were kept open the pain will increase tenfold. The author of this essay is not Muslim, and he commented at the end of the essay: "Those doorways are controlled by man's psychological status".
The believer is pleased with Allah, and in this hospital two persons were admitted with the same cancer and the same pain, however one of them made his room a paradise for every visitor, whereas the other drove people away from him.
There is wisdom in pain.
It has been discovered that there are valves for the pain that can be controlled by the believer. The believer is pleased with Allah and he proves it through his actions.
The delicate point Ustaz Jamal: Salah is an obligation but we should remember that there are great purposes behind Salah.
Allah says:
﴾ And perform As-Salat (Iqamat-as-Salat) for My Remembrance. ﴿
You mention Allah in your Salah. It is said that if you want to talk to Allah, supplicate to Him, and if you want Allah to talk to you, read the Quran.
The believer is treated differently regarding pain. The proof is those doorways that exist on the path of pain to the brain.
The believer by definition is not only the one who offers Salah, as there is a huge difference between the believer and the non-believer. The believer is the one, who knows the secret and the purpose of his existence, and he follows the path that leads to pleasing His Lord, thus he is included in Allah's Mercy and Vacancy.
Allah provided man with a miraculous mechanism:
A friend of mine lives in an Arab country, and he works for a certain ministry. He was sent to China to buy some meat, but when he asked them to slaughter the animals according to the instruction of the Prophet, peace be upon him, they raised the price of the meat, saying, "The animal will lose all its blood." But when the animal is slaughtered according to the common way in the west, it will be hanged from its feet and its head will be cut off completely, and the body will keep most of its blood, why is that?
Ustaz Jamal this needs a little patience to be understood, so I ask the listeners to have patience.
If someone sees a snake while he is walking in a garden, what will happen? The image of the snake is printed on the retina, and the latter sends this image to the brain in the area responsible for the vision. In this area there is a file about snakes, containing the information man gathers through studies, meetings and stories heard about snakes. The brain reads in this file that this is a snake and it is dangerous.
The brain is the king of the nervous system, and this king gives orders to the most critical gland that is considered the queen of hormone glands (the pituitary gland). The signal it receives tells it that there is a dangerous animal whose bite could be fatal, so what does the pituitary gland do in this case?
It sends a hormonal signal to the adrenal gland, which is located above the kidney, asking it to face this danger. In fact, the adrenal gland sends five messages: an exceptional order to the heart to raise its rate from 80 beats to 180 beats per minute. The reason is that a frightened person needs to move and moving requires blood. Thus, the heartbeat is accelerated to 160 or even to 180 beats per minute.
There is a connection between the accelerated heartbeat and the lungs; the lungs expand, so the terrified man breathes quickly. Also, the vessels which give man's face the rosy color, stop working as normal as they receive an order to narrow their lumen. As a result, man turns pale. Furthermore, in such a situation the person needs sugar, so the adrenal gland gives an order to the liver to release extra sugar.
Naturally the sugar in blood is 90 mg/dl, but if we run a sugar test on the blood of a frightened person, it will be 350 mg/dl due to extra sugar released by the liver to be an extra fuel to the muscles, and the liver produces coagulating hormone, so the blood of the scared person becomes thick.
What catches the attention, and this is my advice to the listeners, is that the Nicotine in cigarettes does all the previous symptoms, for it causes the heart to increase its beats, the lungs to expand , the skin’s blood vessels to narrow their lumen, the liver to toss extra sugar and to produce coagulating hormone, and thus the smokers are prone to clots 18 times more than non-smokers.
What a creation?
Ustaz Jamal:
Allah, The Most Glorified, the Most High, says
﴾ And also in your ownselves. Will you not then see? ﴿
Dr. Rateb has talked at length about the following Ayah:
﴾ Verily, We created man of the best stature (mould), ﴿
Dr. the nerves in man have a special importance and they wrap the entire body of man like an endless net, will you please tell the listeners about the function of the nerves and their importance in our life.
The function of nerves and its importance in man's life:
Dr. Rateb:
They have a preventive function and a therapeutic one.
If you push a pin in any part of your skin even as small as one square millimeter, you will feel pain due to the sensory nerves which are spread significantly all over the skin.
Man's nerves are sensory or mobile, or they transmit sense.
Had man's hair been provided with sensory nerves, having a hair cut would have needed a surgery in the hospital under anesthesia, however every hair has its own vein, artery, motor nerve and muscle. One might say: "my hair stands on end" when he is cold.
This means that a muscle is given an order through a nerve thus it stands.
What is the wisdom behind the absence of sensory nerves in the hair?
Having a hair cut is easy because of the absence of sensory nerves in hair.
What is the wisdom behind the absence of sensory nerves in nails?
Had man had sensory nerves in his nails, he would have turned into a monster; this is the wisdom, for man trims his nails because of the absence of sensory nerves.
Why is the existence of sensory nerves very important in bone marrow?
Ustaz Jamal, the importance of having sensory nerves in the marrow is that when man has a fracture in a bone, Allah forbids, the severe pain keeps the bone still which makes 4 fifth of the curing process.
There are also sensory nerves in the teeth because if there weren't any, man might lose all his teeth without even feeling it.
Having a tooth decayed without feeling it makes man lose it.
Contrary to that, the minute the decay reaches the tooth pulp you can't sleep at night, thus the sensory nerves in teeth work as an early warning system.
Wisdom behind the permanence of the cells in the heart and brain:
In fact nerves' function is very useful.
This leads us to the fact that man's body changes, in other words your body changes completely after 5 years; your skin, hair, cornea and every cell without exception.
The shortest age for a cell is the skin's cell which is 3 days, and the longest age for a cell is the bone cell which is 5 years.
Thus man's body is changed completely, and in 5 years nothing in him is the same as 5 years ago.
However, the brain and the heart are the exceptions so they don’t change. The wisdom behind that is very significant.
Had the cells of the brain changed, man would have forgotten his specialty, his knowledge, and his degree.
Had the cells of the brain changed, when a man is asked "what do you do for a living?" he would answer, "I used to be a physician but when my brain cells changed I forgot medicine entirely."
What is the wisdom for having the brain and heart cells unchanged?
I spent 30 years in calling to Allah, and as I see it, the wisdom from having the brain cells unchanged is very clear. On the other hand, the wisdom of having the heart's cells unchanged is not as clear.
After transplanting 300 hearts around the world, it was discovered that the feelings, tastes and tendencies of reciepients of hearts from other people changed. I have more than 300 stories about people who used to hate a kind of food and after receiving the heart transplant they liked that food.
Some didn’t like a kind of music and after receiving the transplant they changed and love it.
In another case, a little girl who received a heart from another girl who was murdered, was afraid all the time to such an extent that she was able to describe the features of the murderer’s face, after which the Murderer was taken into custody.
We used to believe that memory is in the brain, but the amazing discovery is that every cell has a memory.
The more we know the more ignorant we become.
You think you are a very small creature
Whereas the whole world is unfolded within you
﴾ Verily, We created man of the best stature (mould), Then We reduced him to the lowest of the low, ﴿
There are neuron cells in the heart.
Advancemed science reveals the greatness of the Quran:
Ustaz Jamal, upon reading the following Ayah:
﴾ And have they hearts wherewith to understand ﴿
thirty years ago I believed that the heart is the heart of the self, but now, no.
This heart has a pine shape and it is placed in the left side of the chest, this heart has reason.
The power of the neuron cells in the heart is 5000 times more than the brain neuron cells, better yet the heart cells give orders to the brain cells.
Allah says:
﴾ And have they hearts wherewith to understand ﴿
This means that the more advanced science becomes, the more layers of greatness are discovered in this Quran.
By Allah Ustaz Jamal, after I read this research, I had another perspective of the Ayat in Quran that mention the heart, and the clearest of which is the following Ayah:
﴾ And have they hearts wherewith to understand ﴿
This means that the neuron cells in the heart are more powerful than those in the brain, and they even give orders to the brain.
The other thing is that the neuron cell has a memory unlike what we used to believe that it is the man who has memory, and the proof is in the following Ayah:
﴾ On the Day when their tongues, their hands, and their legs or feet will bear witness against them ﴿
This means that cells have memory.
Ustaz Jamal:
It is the truth when Allah says:
﴾ Verily, We created man of the best stature (mould), ﴿
Allah Almighty has spoken the truth, He is Great and Creative, and it is He whom we want to be with.
I hope that we are with Allah so that He will be with us. We are with Him in worshiping, obeying and drawing closer to Him. He deserves to be worshiped.
