They are deaf: unable to hear and accept the truth, or speak about it. They are blind to seeing the truth, so they do not turn back from their error.
Their likeness is as the likeness of one who kindled a fire; then, when it illuminated all around him, Allah removed their light and left them in darkness. (So) they could not see (17)They are deaf, dumb, and blind, so they return not (to the right path)(18)
The Example of the Hypocrites
Allah likened the hypocrites when they bought deviation with guidance, thus acquiring utter blindness, to the example of a person who started a fire. When the fire was lit, and illumnitated the surrounding area, the person benefited from it and felt safe. Then the fire was suddenly extinguished. Therefore, total darkness covered this person, and he became unable to see anything or find his way out of it. Further, this person could not hear or speak and became so blind that even if there were light, he would not be able to see. This is why he cannot return to the state that he was in before this happened to him. Such is the case with the hypocrites who preferred misguidance over guidance, deviation over righteousness. This parable indicates that the hypocrites first believed, then disbelieved, just as Allah stated in other parts of the Qur'an.
Allah's statement,
ذَهَبَ اللَّهُ بِنُورِهِمْ
(Allah removed their light) means, Allah removed what benefits them, and this is the light, and He left them with what harms them, that is, the darkness and smoke. Allah said,
وَتَرَكَهُمْ فِي ظُلُمَـٰتٍ
(And left them in darkness), that is their doubts, disbelief and hypocrisy.
لاَّ يُبْصِرُونَ
((So) they could not see) meaning, they are unable to find the correct path or find its direction. In addition, they are,
صُمٌّ
(deaf) and thus cannot hear the guidance,
بُكْمٌ
(dumb) and cannot utter the words that might benefit them,
عُمْيٌ
(and blind) in total darkness and deviation. Similarly, Allah said,
فَإِنَّهَا لَا تَعْمَى الْأَبْصَارُ وَلَٰكِن تَعْمَى الْقُلُوبُ الَّتِي فِي الصُّدُورِ
(Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind)(22:46) and this why they cannot get back to the state of guidance that they were in, since they sold it for misguidance.
The last four verses bring out the miserable plight of the hypocrites with the help of two extended similes. The choice of two examples is meant to divide the hypocrites into two kinds of men. On the one hand were those in whom disbelief had taken deep roots, so that they had little inclination towards Islam, but pretended to be Muslims for worldly motives - the Holy Qur'an compares them to the man who, having found light, again loses it, and is left in darkness. On the other hand were those who did recognize the truth of Islam, and sometimes wished to be genuine Muslims, but worldly interests would not allow them to do so, and they remained in a perpetual state of hesitation and doubt - they have been likened to the men caught in a thunderstorm who move forward a step or two when there is a flash of lightning, but, when it is over, again get stuck. In the course of these parables, the hypocrites have also been warned that they are not beyond the power of Allah, and that He can, as and when He likes, take away their sight and hearing, and even destroy them.
In a dark room black and white look the same, but as soon as the lights are turned on, black appears as black, and white as white. The same is true of the message of God, which was revealed to the prophets. The divine scriptures are God’s beacons to the world. When this light is shed upon mankind, guidance and error clearly appear for what they are. It becomes evident what good and evil deeds consist of, and what their consequences are. But some people, instead of bowing to the truth, want the truth to be subservient to them. The light of God only serves to confuse them. Their hidden jealousy and pride take hold of them. As soon as they see themselves in the divine mirror, their negative sentiments are aroused. Deep-rooted prejudices overcome their senses. They have eyes, but cannot see; they have ears, but cannot hear; they have tongues, but cannot speak. They can neither hear the call of truth, nor respond to it in any way, nor can they find their way by any sign from God. Instead of reflecting upon the call of truth, as they should do, they evade it either by attaching no importance to it, or by not listening to it at all.
