It is Allah Who Created Beavers
So you've learnt about beavers along with Karim. As you've seen, thanks to skills possessed at birth, these new friends of Karim can design buildings, which is in fact quite a difficult and complicated task. Then they carry out this plan with great skill. Unlike Karim's sister, beavers do not go to school, nor are they trained for years. But they know exactly what to do, because there is a Supreme Being Who teaches them all these things. This being is Allah, Who created everything, including us.
Remember! A beaver could not have acquired the skill to build dams by chance. It could not have made its body just right for its needs. It could not have discovered by itself the shape to build the dams so that they should be strong enough to withstand the water pressure. And more importantly, it could not have ensured other beavers' possessing the same skills.
There is one more point to note: Beavers could not live if even one of the features they possess were lacking. For example let's consider their teeth. If their back teeth, though not worn down, kept growing like the incisor front teeth, they would become too large, would apply pressure on the jaw and make it impossible for the beaver to use its mouth.
How would the beaver gnaw trees and build dams in this case? How would it build its home? Of course it would not be able to do any of these things. It would not even be able to feed because of the structure of its mouth, so it would eventually starve to death.
Moreover, many organs other than its teeth are especially created for the tasks they perform. Transparent eyelids to protect its eyes when under water as well as special mechanisms that close its ears and nostrils to keep water out are special features which beavers have. Besides these, a beaver has webbed back feet and a stiff, flat tail, which help make the animal a powerful swimmer. These are all advantageous features a beaver has at birth.
You must have understood now why Karim has been so amazed by his little friends.
Karim's little friends possess this body structure, and knowledge and skills to construct dams at birth. All beavers build their homes with Allah's guidance and act in accordance with what He has "inspired" them to do. It is Almighty Allah Who has created these creatures and given them these superior skills.
Allah created all living things with the features that are most appropriate for the tasks they carry out and that fully meet their requirements.
Allah is compassionate to all beings. As Allah states in the Qur'an:
Your god is Allah alone, there is no god but Him. He encompasses all things in His knowledge. (Surah Ta Ha: 98)
