The diversity and variety of species are often mentioned in the Qur’an. And it is the same for the importance of pairs, as complementary differents.
“He created the heavens
Without any pillars that you
Can see ; He set on the earth mountains
Standing firm, lest it
Should shake with you ;
And He scattered through it
Beasts of all kinds.
We send down rain
From the sky, and produce
On the earth every kind
Of noble creature, in pairs.
Qur’an 31-10
“And among His Signs
Is the creation of the heavens
And the earth, and the variations
In your languages
And your colours : verily
In that are Signs
For those who know.
Qur’an 30-22
