Birds:

Dr. Nabulsi:

Birds have breathtaking colors; as if they are genetically programmed to have these colors. The red color, for example, is very sharp. Ustaz Adnan, who do you think inspire the designers of colors? Birds and butterflies inspire them. All the outstanding colors we have are inspired by the colors of birds.

Allah has given birds the suitable, adjusted and exact needed colors. As you know the red color, for example, has various shades that might reach 1000. Also, when we use other colors, they might have 3380 shades. In fact, all the shades of colors are found in birds. 

What bewildered Darwin, the founder of evolution theory, was the colors he saw on birds, like peacock, as the colors that are so marvelous like that cannot  exist accidentally, which opposes his theory.

The fascinating colors of birds are Signs of The Creator Almighty:

Should you observe the beauty in butterflies and birds with all their charming colors, you will be amazed. The believer always senses the beauty in the creations of Allah the Almighty. Well, the unbeliever enjoys the artificial beauty unlike the believer whose soul is inspired by the absolute beauty. When we rejoice the beauty in life, we will sense a touch of Allah's Beauty. Furthermore, if we establish a connection with Allah the Almighty, we will establish a connection with beauty and perfection. Thus, the believer is given happiness that is enough for an entire country. 

Birds have colors and streamlined bodies, and so they are likeable to everyone. Allah the Almighty says:
 

﴾ And We have subdued them unto them﴿ 

[Ya-Sin, 72]

Some animals are meant to be likeable to man, like birds, whereas other animals might have the same size birds have, with streamlined bodies, yet they are very scary, like snakes for example. Allah the Almighty says:

﴾ And We have subdued them unto them﴿ 

[Ya-Sin, 72]

Allah, Exalted and Sublime, be He,  also says:

﴾And there is not a thing but glorifies His Praise. But you understand not their glorification. ﴿ 

[Al-Isra', 44]

﴾ He is Allah, the Creator, the Inventor of all things, the Bestower of forms. To Him belong the Best Names. All that is in the heavens and the earth glorify Him. And He is the All-Mighty, the All-Wise.﴿ 

[Al-Hashr, 24]

Ustaz Adnan:

We ask Allah the Almighty to direct us to the path of repentance, especially by reflecting on Allah's creations as you already have mentioned so that we may fulfill the purpose of their creation.
