[Pooya/Ali Commentary 2:7] Sealing of the disbelievers' hearts, who make a willing choice of the life of sin, is a happening in the usual course. Lack of proper use of the faculties of discernment and understanding blunts their judgement and reasonableness, a logical penalty, referred to in verse 179 of al Araf, and verse 5 of Ha Mim, wherein they themselves bear witness to the penalty they had been inflicted with. According to the commentator of Majma ul Bayan, seal means witness or testimony. Allah bears witness to the loss of usefulness of the disbelievers' faculties to see, hear and understand, in order to inform the Holy Prophet that all attempts, howsoever sincere and eager, will fail to bring them back to the right path, as they are unable to pay attention to any type of warning. Aqa Mahdi Puya says: As has been explained on page 24, in the commentary of verse 5 of al Fatihah, man's action is in fact a reaction to Allah's action which becomes active in response to the complex of essential qualities of the object which reacts. QULUB Aqa Mahdi Puya says: Qalb (heart) in the Quran, refers to the functions of the conscious self. It is the centre of total human consciousness, known as "I", like the physical heart which is the centre of the blood circulation system. The mind receives information ; through the experiences of the senses, which are developed into ideas by a mental operation, which also perceives feelings. These feelings are translated into actions, and the actions return back to the mind, undergoing the same process. It resembles the circular movement of the blood into the physical heart. Another justification is the close relation of the feelings with the physical heart, the main organ of the body, which, moved by the feeling, acts. The qalb reacts to the suggestions and guidance received through the experiences of the senses as well as subjective insight, corresponding to the individual peculiarities. Some qalbs are more receptive to goodness, refined thoughts and feelings of a higher spiritual nature. Some qalbs are more inclined towards evil and worldly pleasures. A "one and the same" suggestion may cause different reactions in the two directly opposite qalbs. One qalb receives the divine command and carries it out, while the other rejects it and revolts. The immediate organ between the heart and the divine preaching is the ear, therefore, it has been connected with the heart, and as the result of the sealing of the heart, the ear has also been sealed. Consequently the disbelievers' vision has been obscured. Now they cannot see the truth. For them is a painful torture in the hereafter.
