PERFECTION OF LIMBS AND MEANS FOR THEIR PROTECTION

Al-Musaawir  has created His creation with incalculable perfection, wisdom, and beauty.
Understand this point in the light of these examples:

1) An animal cannot clean its ears. Therefore around its ears, countless strands of hair have been placed which does not allow dust particles and insects to enter.

2) The ears of chickens, ducks and other birds have been closed protecting it from dust particles. In the ears, a certain liquid has been placed that insects abstain from entering therein, due to its bitter taste. In this manner, Allaah Jalla Jalaalahoo has created means for the protection of the auditory organs; else man and animals would quickly become deaf.

3) By means of seven veils, He  has protected the light of the eyes. Allaah Jalla Jalaalahoo has fixed the eye – the most delicate part of the body – in a cavity. This is surrounded by the bones of the nose and bridge. The eyelashes and eyelid has been created so sensitive that as soon as any foreign object appears, it closes. The eyes of animals which are hunted, are placed in an even deeper cavity so that the hunter cannot cause any injury to it. The brain stores an electrical house which continues assigning power and light to the eyes. 

4) The nostrils have been constructed curved. For protection from dust particles, hairs have been placed inside the nostrils in order to ensure that the air is filtered and therefore saving man and animals from colds and catarrh. 

5) In the nose is such a liquid which does not allow any insects to enter. In this way, Al-Musawwir has preserved the sense of smell.

6) In the throat, windows have been erected so that food particles can enter its passage and the air can enter its passage. 

7) Like the holes in the throat, Allaah Jalla Jalaalahoo has made the stomach curved so that the food remains in the stomach and does not emerge.  

Hafiz Ibn-Katheer Rahimahullaah has written, “From the time Allaah Jalla Jalaalahoo Created Sayyiduna Adam Alayhis Salaam till Qiyaamah, every person has two eyes, two eyebrows, a nose, a forehead, a mouth, and two cheeks. No person resembles the other exactly. There definitely is some difference in their qualities, features, or speech, whether it be apparent or concealed, but realized when one ponders deeply. Every face has its own form and feature which does not resemble another. If a group of people have to be found who seem similar to each other in attractiveness or unattractiveness, then too (by careful inspection) one will definitely find a difference between them."
