be needed to accomplish these tasks. Even if one managed to do this in such a small space, the performance and results would still be inadequate. One might manage to purify water or other fluids, but doing so for blood, which is essential for human beings, has not yet been achieved in such a small device.

However, all human beings are actually perfect examples of this special purification system, thanks to the kidneys, each one of which is about 10 cm (4 in) in size and weighs 100 grams (3.5 ounce). This small space harbors around 1 million micro-purifiers that constantly clean the blood, which carries everything that makes continued life possible, and regulate the density of the water that reaches all of your cells and tissues. The kidneys,that they have all been equipped with similar and sometimes vital details.

One such detail is water. At sub-zero temperatures, water turns into ice. This is just one of many natural phenomenon in our lives, and yet this transformation violates the known laws of physics. The special details in water, created by Allah for a specific purpose, are one of the reasons why life on Earth exists.

All known substances contract as their temperatures fall. As liquids contract and lose volume, their densities increase and their cold parts become heavier. This is why matter's solid state is always heavier than its liquid state. We can cite the liquid and solid states of steel as an example of this. Contrary to all other known liquids, however, water contracts until it reaches
