The perfect detail that protects ice-dwelling polar bears

The human body contains many extraordinary systems. How they work, function uninterruptedly, take precautions in the face of difficulties, and never make a mistake is beyond belief. However, all living things on Earth, from giant whales to ants, from single-celled algae to tigers, have equally amazing features. It is literally miraculous that anyone witnessing this extraordinary state of affairs should still deny the works of Allah:
 

Even if We sent down Angels to them, and the dead spoke to them, and We gathered together everything in front of them right before their eyes, they would still not believe unless Allah willed. The truth is that most of them are ignorant. (Surat al-An‘am, 111)
 

Let us take the example of polar bears, who live in a cold ice-shrouded environment. By grasping the surface of the ice via a vacuum effect, by way of the cavities between its toes, a polar bear can travel long distances on ice. This web-like structure between its toes also enables it to walk at a speed of 10 km per hour (6.2 mph) and travel 100 km (62 miles) without resting. The apparently white hairs in its special 5 cm (2 in) thick fur are actually transparent and, because of their fiber optic properties, prevent heat loss and transmit the Sun’s warmth to the black hairs beneath. Immediately under the fur is a 10 cm (4 in) thick layer of fat that provides further protection against the cold. When it swims, its hairs form a protective shield by adhering to one another and serving as a waterproof diving suit. Thanks to all of these features, a polar bear can maintain its 37-degree body temperature under water or on the ice.
 

Such highly detailed and flawless structure reveal that it could not have come about by chance. Moreover, scientists cannot produce them. Allah flawlessly creates all things. In the case of the polar bear, He places this animal on the ice and enables it to survive its harsh environment. This is a constant reminder of the greatness of Almighty Allah, Who creates the states and behavior of all things by His will:
 

And He has made everything in the heavens and on Earth subservient to you. It is all from Him. There are certainly Signs in that for people who reflect. (Surat al-Jathiyyah, 13)
