Al Anfāl

إِنَّ شَرَّ الدَّوَابِّ عِنْدَ اللَّهِ الَّذِينَ كَفَرُوا فَهُمْ لَا يُؤْمِنُونَ

55 . “Verily the worst of animals in Allah's sight are those who disbelieve, so they will not have faith.”

In verse No. 22 from the current Surah, the meaning of the Qur'anic phrase /sarr-ad-dawabb/ (the worst of animals) was introduced as ‘those who do not contemplate’, while here, in this verse, they are defined as ‘those who disbelieve’. The verse says:

So, the origin of infidelity is the absence of right intellect. The Qur’an considers the feature of humanity of man in wisdom and belief, so that if he does not contemplate or paves the way of infidelity, he will be out of the circle of humanity. Thus, a true human, indeed, is the one who is wise and has Faith. It is possible that a disbeliever has a title and rank with the people of his society, but he is ‘the worst of animals’ in the sight of Allah.

It is cited in some commentary books that the referent of a concept of this verse is the Jews, but this idea does not harm the generality of the concept of the verse. However, those who hear the call and invitation of prophets, and do not show any positive reflection to it, are ‘the worst of animals’.
