27, verse 80) Sometimes they are resembled to beasts: “...and eat as the beasts eat...”. (Surah Muhammad, No. 47, verse 12) Sometimes they are introduced worse than the beasts, as the Qur'an says: “...they are as cattle, rather they are more astray...” (Surah Al-‘A’raf, No.
7, verse 179) Sometimes they are considered as the worst creatures, as the verse under discussion says: “Verily the worst of animals in the sight of Allah...” Since ‘the statements’ which are not fulfilled accordingly and ‘the hearings’ which are uneffective in action are counted one of the greatest afflictions of the human societies, which can be the origin of kinds of misfortunes, again the Qur’an emphasizes on this subject once more in this very verse, and in a delicate and nice statement, it follows that meaning by saying: “Verily the worst of animals in the sight of Allah are the deaf, the dumb, who do not understand.” Also, in view of the fact that the Qur’an is the Book of practice, and not merely a ceremonial book, thoroughly it lays emphasis on the consequences of deeds.
In this verse, too, those who have safe ears but they do not pave the way of hearkening to the revelations of Allah, and do not follow the words of truth and the programs which lead to happiness, are considered as earless persons. And, those who have a sound tongue but keep silence when they should defend the truth are considered as some deaf and dumb persons.
Such people neither struggle against injustice and mischief, nor do they lead the ignorant, nor do they enjoin what is right and forbid what is wrong, nor do they invite others to the way of truth, but they apply this great bounty of Allah in the way of idle talks, backbiting, flatteries before the possessors of wealth and power, or they often make use of it for perverting the right and strengthening the falsehood.
Some of them are not ready even to listen to the truth.
