The third verse (22) strongly condemns those who do not listen to what is the truth thoughtfully and let it go unaccepted. The Qur'an has declared such people to be worse than animals. The words used are: إِنَّ شَرَّ الدَّوَابِّ عِندَ اللَّـهِ الصُّمُّ الْبُكْمُ الَّذِينَ لَا يَعْقِلُونَ ﴿22﴾ (Surely, the worst of all animals in the sight of Allah are the deaf and the dumb who do not understand).
The word: دوابّ (dawabb) is the plural form of: دَآبَّۃ (dābbah). Literally, everything that walks on the earth is called 'dābbah.' But, in usage, only quadruped animals are called 'dābbah.' So, the sense of the verse is that the worst quadrupeds in the sight of Allah are the ones deaf against listening to the truth and dumb when it comes to accepting it. Even someone deaf and dumb could, if he has the least fund of reason in him, make himself understood by simple gestures in a two-way communication. But, these people are not only deaf and dumb, they are short on reason also. It is obvious that for a person, who is deaf, dumb; and devoid of reason too, the lines of communication shall remain blocked and there will be no way they would understand or be made to understand.
In this verse, Allah Ta` ala has made it clear that human beings have been created with the best of destiny. They have been made the superior-most among the created and the universe has been placed at their service. These are great blessings which lie embedded in and dependent on listening to truth and obeying it. Once human beings turn their backs on listening to the truth, understanding and accepting it, all these blessings are sucked away from them and they are relegated to some species worse than animals.
It appears in Tafsir Ruh al-Bay-an that human beings are, in terms of their original creation, superior to all animals, but are lower in rank as compared to angels. But, when human beings strive on the pathway of obedience to Allah, their creator, they rise higher in status than angels too. However, should they turn away from the pathway of obedience to Allah, they are condemned to become the lowest of the low, far too worse than animals.
