From another point of view...
From another point of view, the Noble Qur'an believes in a particular form of seeing, hearing, understanding and comprehending other than the apparent understanding of these powers just as it is said in regards to the open disbelievers: صُمٌّ بُكْمٌ عُمْـيٌ فَهُمْ لاَ يَعْقِلُونَ “Deaf, dumb, and blind, they do not understand anything.”[^5] In another place in the Qur'an, the hypocrites are referred to as having a sick heart and since they do not want to change, Allah (SwT) adds to their sickness: فِي قُلُوبِهِمْ مَرَضٌ فَزادَهُمُ اللٌّهُ مَرَضاً “In their hearts is a disease (and due to their obstinacy) Allah has added to their sickness.”[^6] Those who do not have the fear of Allah (SwT) within themselves are introduced as people possessing hearts of stone - rather, their hearts are even harder and firmer than stones: ثُمَّ قَسَتْ قُلُوبُكُمْ فَهِيَ كَالْحِجَارَةِ أَوْ أَشَّدُّ قَسْوَةٍ “Then your hearts hardened after that, so that they were like rocks, rather worse in hardness;”[^7] In relation to a group of disbelievers, there is a phrase that is used in the Qur'an in which they have been referred to as being impure: أُولٌئِكَ الَّذِينَ لَمْ يَرِدِ اللٌّهُ أَنْ يُطَهِّرَ قُلُوبُهُمْ “Surely those are the people whose hearts are not purified by Allah.”[^8] In another place in the Qur'an we read that the only ones who shall hear and respond to the call of the Prophet (S) are those who are spiritually alive and possess the ears to hear such a call: إِنَّمَا يَسْتجِيبُ الَّذِينَ يَسْمَعُونَ وَالْمَوْتى يَبْعَثَهُمُ اللٌّهُ ثُمَّ إِلَيْهِ يُرْجَعوُنِ “The only people who shall accept and answer (your call) are the people who (spiritually) hear you and as for the (spiritually) dead, Allah will raise them, then to Him they shall be returned.”[^9] From these different phrases and indeed many other similar phrases in the Qur`an, we can clearly see the angle which the Qur`an takes on life and death and that it is the humanistic and logical angle of the discussion since all of the worth of a person is contained and based on this aspect of his life (his spiritual traits and worth and not his physical existence).
The factors that determine a spiritual death and life are very many, however undoubtably things such as hypocrisy, pride, prejudice…
