Ан-Ниса 4:50

The Jews were thought to be the representatives of the religion of God. Hence, when non-Jewish Arabs started supporting the Prophet, the Jews became his opponents to save the facade of their religiousness. In this way their being misguided did not remain confined to themselves and they began to raise controversies about the life and teachings of the Prophet. This was to confuse people and to prove that he was not the Messenger of God but a self-proclaimed proponent of religion working towards fulfilling his ambition of becoming a leader. God is, however, not indifferent in this matter: He will surely side with the faithful and make them successful against misguided opponents. Accursedness is, in fact, the extreme form of man’s insensibility. When he becomes too insensitive to distinguish between right and wrong, this has been called the state of being accursed. An individual often hears something without its registering upon him. This happens at a time when he is not serious about heeding the divine message. As this attitude becomes more established, the person becomes irresponsive, as if the features of his face had been obliterated and he is seeing and listening with the back of his head where there are neither eyes nor ears. Such blindness and deafness to the truth and reality indicate that God has deprived that person of His blessings due to his constant negligence of truth and reality. God had provided him with ears, but he could not listen; God had given him eyes, but he failed to observe. God, therefore, made him exactly the same as what the individual had actually turned himself into. This extreme stage of insensitivity takes the form of ‘maskh’, that is, a metamorphosis from a superior state to an extremely inferior state; man, the most superior form of creature, is degraded to the level of the beasts.
