Surely, the worst creatures in the sight of God are the deaf and dumb who do not use their intellect/reason. [8:22]
Sir, this makes absolute sense. If we humans do not use intellect, we would be worse than animals. Animals at least can work through their God-given instincts. Without using reason, we are no better than chickens without heads.
QXP 8:22 The worst of created beings in the Sight of God are the deaf and the dumb, those who do not use their intellect. [2:18, 16:76]
16:76. God gives you another example of two men. One of them is he whose faculties of speech and mind are disabled. He cannot do anything of his own accord and he is wholly dependent on his care-provider, unable to bring forth any good. Can such a one be equal to the man who is fit, enjoins justice and himself walks the straight path? [God expects humans to use their faculties in the best manner]
