What we see and what we do not ..!
Are there really things around us that we cannot see?
A quick look to the nature of light, being the tool of vision and sight, can help bring home the idea.
- There is a difference between visible light and light in general.
- Light scale in general starts with less than 0.1 of the nanometer, as in the case of rays of short wave and high power (Gamma rays), up to more than 1 km, as in the case of long waves and low power (Radio waves).
- Visible light is the light waves that man’s eyes can receive and through which he can see things. This has no significant rate in the wave length scale of light or in electromagnetic waves, where normal light waves with its seven known colours reach a rate of 400 and 800 nanometers (nanometer is one thousand-millionth of a meter) on the scale grade.
- Man with the help of visible light can see all around, as he can see microorganisms through microscopes and far celestial bodies through telescopes. Man was not able before the discovery of these two instruments to see more than his open eye could see. Man can presumably see all that which can be seen by visible light, regardless of being minute or huge. This gives the room for the question: what about other unseen worlds?
- What is the volume of these visible things in the direct light waves in comparison with the things that cannot be seen or perceived by the human eye?
Here are the different types of famous rays and their existence on the wave length scale, arranged in an ascending order as per the length of waves and in an descending order as per the power range:
- Gamma Ray. Its length is less than 0.1 of the nanometer, and is considered of the highest power.
- X-ray. Its wave length reaches up to 1 nanometer and is high in power and can penetrate lots of substances. It is commonly used in the medical field.
- Ultraviolet ray. Its wave length reaches up to 100 nanometers and is originated from stars explosion, and the sun as well bursts huge amounts of such a ray.
- Visible light. The length of different waves ranges between 400 – 800 nanometers.
- Infra-red ray. It length is 0.1 of the nanometer and is usually originated from hot substances and every living being. This ray is used by armies to locate targets of machineries and soldiers that emit heat. Lots of snakes use it to determine their quarries precisely.
- Short waves or microwaves. These are used in telecommunications (specially in mobile phones), and commonly used heaters. They are used as well in guiding planes, and in determining the speed of traffic on roads.
- Radio waves. They range between one meter to 1 km in length and are originated from stars as other rays, as well as the lightening processes in clouds, and can be received by radio sets. They are used in wireless telecommunications in general.
“I swear by that you see and by that you do not see.” (69:38-39)
فَلاَ أُقْسِمُ بِمَا تُبْصِرُونَ . وَمَا لاَ تُبْصِرُونَ [ سورة الحاقة 38-39].
The origin of creation : clay & water !
In the Quran, Allah reveals that the creation of man is a miracle. The first human being was created by Allah shaping clay into a human form and then breathing a soul into it, Allah (SWT) says in Quran : ( Your Lord said to the angels, “I am going to create a human being out of clay. When I have formed him and breathed My Spirit into him, fall down in prostration to him!”) (Quran 38:71-72)
إِذْ قَالَ رَبُّكَ لِلْمَلَائِكَةِ إِنِّي خَالِقٌ بَشَراً مِن طِينٍ (71) فَإِذَا سَوَّيْتُهُ وَنَفَخْتُ فِيهِ مِن رُّوحِي فَقَعُوا لَهُ سَاجِدِينَ (72) [ سورة (ص) 71-72].
and also says : ” Then inquire of them: Is it they who are stronger in structure or other things We have created? We created them from sticky clay ” (Quran 37:11)
فَاسْتَفْتِهِمْ أَهُمْ أَشَدُّ خَلْقًا أَمْ مَنْ خَلَقْنَا ۚ إِنَّا خَلَقْنَاهُمْ مِنْ طِينٍ لَازِبٍ [ سورة الصافات 11].
When the human body is examined today, many elements present on the earth are also discovered to be found in the human body. Living tissues contain 95% carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur, with a total of 26 different elements.91 In another verse of the Quran we are told:“We created man from an extract of clay” (Quran 23:12)
وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن سُلَالَةٍ مِّن طِينٍ [ سورة المؤمنون 12].
The Arabic word “sulala,” translated as “extract” in the verse, means “representative example, essence.” As we have seen, the information revealed in the Quran 1,400 years ago confirms what modern science tells us-the fact that the same elements as those found in the soil are employed in the human creation .
Below is a diagram showing the distribution of the elements in a 70-kilo human being.
As we notice above water forms the main component of the human being and any other being . Allah (SWT) says :
” Allah created every [living] creature from water. Some of them go on their bellies, some of them on two legs, and some on four. Allah creates whatever He wills. Allah has power over all things” (Quran, 24:45)
وَاللَّهُ خَلَقَ كُلَّ دَابَّةٍ مِن مَّاء فَمِنْهُم مَّن يَمْشِي عَلَى بَطْنِهِ وَمِنْهُم مَّن يَمْشِي عَلَى رِجْلَيْنِ وَمِنْهُم مَّنيَمْشِي عَلَى أَرْبَعٍ يَخْلُقُ اللَّهُ مَا يَشَاء إِنَّ اللَّهَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ [ سورة النور 45].
” and We made from water every living thing? So will they not believe?” (Quran, 21:30)
وَ جَعَلْنَاْ مِنَ المَاْءِ كُلَّ شَيْءٍ حَيٍّ أَفَلاْ يُؤْمِنُوْنَ [ سورة الأنبياء 30].
“And it is He Who created human beings from water and then gave them relations by blood and marriage. Your Lord is All-Powerful” (25:54)
وَهُوَ الَّذِي خَلَقَ مِنَ الْمَاء بَشَراً فَجَعَلَهُ نَسَباً وَصِهْراً وَكَانَ رَبُّكَ قَدِيراً [ سورة الفرقان 45].
When we look at the verses concerned with the creation of human beings and living things, we clearly see evidence of a miracle. One such miracle is of the creation of living things from water. It was only possible for people to come across that information, clearly expressed in those verses, hundreds of years afterwards with the invention of the microscope.
All life forms need water in order to survive. Animals in dry regions, therefore, have been created with mechanisms to protect their metabolisms from water loss and to ensure maximum benefit from water use. If water loss takes place in the body for any reason, and if that loss is not replaced, death will result in a few days. The famous 17th century scientist Jan Baptista van Helmont discovered in 1640s that water in the soil was the most important element of plant development.
